Chevrolet Silverado 1500 won’t start – how to fix it?
The concern that a costly fault is to blame for the starting issues of a Chevrolet Silverado or a GMC Sierra is often baseless, according to research. Often, the root reason is one that is rather simple to address. A look at the 2020 Chevrolet Silverado LTZ (photo by Chevrolet) Although there are several probable causes for a Chevy Silverado 1500 not to start, there is a limited number of solutions. It might be anything from a simple shortage of gasoline to a depleted battery to a faulty ignition switch.
A vehicle’s starting troubles might manifest itself in a variety of ways.
If the underlying problem isn’t resolved, the vehicle won’t start in those instances as well.
In this case, the vehicle’s behavior when the ignition key is turned on is a first indicator of the issue that was causing the troubles.
Battery empty
Freezing conditions cause car batteries to become clogged and their capacity to decrease. As a result, you are no longer able to fully charge your phone while driving. As a result, the majority of start-up issues occur on cold winter mornings. The starter will hardly turn and the current in the interior will fluctuate, which are both symptoms of a low or even a damaged battery, respectively. It is also conceivable that nothing happens when the ignition key is twisted if the vehicle’s battery is fully depleted of its charge.
- By turning on the inside illumination, you can quickly identify when a power storage unit is completely depleted of energy. When attempting to start the truck, if the light dims dramatically, it is most likely due to a low battery. The charge level of the battery, on the other hand, can only be accurately determined by utilizing a voltage measuring equipment.
How to fix it
When the battery is completely depleted, a jump start is required in order for the vehicle to restart. You should always keep an appropriate jumper cable in the trunk of your vehicle. The battery gets a current pulse from another vehicle, which is sufficient to start the car with its assistance. While the motor is operating, the battery can then be recharged and recovered from its discharge. The use of a battery charger is still another alternative. If the battery, on the other hand, is faulty, only an exchange in the workshop will assist.
This is very important to remember!
Defective starter motor
If the battery is in good condition, a problem with the starter may be the root reason of the vehicle’s inability to start. The starter might be damaged as a result of age-related wear or a material flaw. When attempting to start the computer, a clicking sound is frequently heard.
The component, which is driven by an electric motor, is responsible for using the current from the battery to start the engine and propel it forward. A faulty magnetic switch on the starter might potentially cause the vehicle to be unable to begin operating.
How to fix it
It is extremely unusual that a starter can be repaired. It is also tough to reach because of its location deep within the engine compartment. If the car is going to be lifted anyhow for inspection, it is best to replace the item as a safety measure. This is especially true in the case of older automobiles.
Ignition lock defective
Modern vehicles are fitted with a start button rather than the traditional ignition lock seen on older models. Another fault, on the other hand, can arise in vehicles that still have the ignition lock installed. The fact that nothing happens when the ignition key is turned is generally indicative of this. There is no indication of a bulb being lit, nor does the starter make any noise. In current autos, a fault in the chip card or the chip implanted in the key might cause difficulties that are similar to those described above.
How to fix it
Only the repair of the damaged ignition lock or the replacement of the defective chip card Or the replacement of the defective key would restore the car’s ability to start.
Fuel tank empty
Only the repair of the broken ignition lock or the replacement of the damaged chip card Or the replacement of the defective key would restore the car’s ability to begin running again.
How to fix it
It is typically sufficient to simply replenish the gas tank and start the vehicle with a gasoline engine. Occasionally, it is required to bleed the fuel system in diesel engines. In earlier automobiles, bleeding may be accomplished manually, however in current vehicles, bleeding is accomplished with the use of an on-board diagnostics (OBD) system in conjunction with the appropriate diagnostic software.
Fuel system problems
Even though there is enough gasoline in the tank, it is possible that the fuel will not get into the cylinders and the engine will not start. A faulty fuel pump or injection system are two possibilities for the problem. Incorrect configuration of these components might potentially cause difficulties with the start-up process.
How to fix it
A workshop is required to replace any damaged components of the fuel system. Repairs are almost never feasible. The start-up difficulties, on the other hand, may be resolved quite quickly if the erroneous configuration is used.
Marten bite, lack of ignition spark and other causes
Damage to the martens is another factor that contributes to vehicle starting issues. It is more common for animals to nibble cables and wires in automobiles. These have the potential to interfere with the electrical circuit as well as the gasoline and oil supplies. Taking a peek inside the engine compartment and looking for evident damage may be beneficial if the car does not start. If these items can be located, towing to the next workshop will be necessary. Damaged spark plugs or glow plugs, as well as loosened plug connections on the ignition wires, can all result in a vehicle failing to start.
While damaged candles are difficult to notice by the untrained eye, unsecured plugs are rather simple to repair. In an emergency, the breakdown service or the workshop of choice can be of assistance. It is capable of replacing the faulty components on the spot, allowing the vehicle to restart.
Other possible causes of a non-starting vehicle:
- Foreign objects in the fuel filter
- A faulty crankshaft sensor (which causes the control unit to be unable to determine whether to inject or ignite)
- And a faulty fuel pump. The presence of moisture in the engine
- Fuel line that is clogged
- Engine damage against a repaired engine
- Carburetor that has been flooded (older versions)
- Faulty ignition coil
Conclusion
There are a variety of reasons why the car will not begin to run. When looking for the source of the problem, it is best to follow the exclusion principle and start with the most obvious reason, which is a dead battery. In any event, it is recommended that non-professionals call a breakdown service or a workshop for assistance. The latter has the ability to directly commence repair in the case of a malfunction.
Update on no start problems
I believe I may be experiencing an injector problem. I’ll start by listing the symptoms and what I’ve done to diagnose the problem, but the one thing I can’t seem to find on this site or on the internet is information on how to change the fuel injectors in my L86 engine, which is a pain. GDI engines are not as straightforward as port fuel injection engines, and I understand that, but I believed there’d be something out there. It’s a no-go. I’m fairly sure I’ve read every single topic on this site concerning cold start/injector difficulties, so please excuse me if I repeat something that has already been mentioned.
- Rather than repeat any previous posts, I’d want to hear other people’s thoughts on my problem and their own experiences with replacing these GDI injectors.
- I only use 93 octane fuel, and I make sure that all of my scheduled maintenance is handled on time or early.
- Symptoms/Diagnosis My problem is merely a cold start problem, and it’s sporadic at best, but it’s becoming more regular lately.
- When I conducted an auto-start in my driveway at roughly 70k miles, the cold start problem appeared for the first time.
- When I opened the door and glanced at the rpms, I noticed that they were jumping all over the place.
- It started up flawlessly when I emptied the cache.
- I completed this task the next weekend using the original ACDELCO iridium plugs and Taylor 10MM racing wires (much better than stock).
Fast forward to around three weeks ago, when it did it again after spending the entire day in the parking lot at my place of employment.
I added a CAI system (aFe Power Momentum GT) approximately 72k miles ago, and I was wondering whether I had accidently screwed up the MAF sensor during the installation process (even though it was fine for 3k miles).
Until a week ago, when it had another tough cold start but didn’t throw a code, everything seemed good.
This week has seen two shaky starts, with one stalling immediately after starting, and the situation is becoming progressively worse, as shown in the graph.
I happened to be borrowing a tech equipment and ran a diagnostics check on the cylinders, which revealed that cylinder 3 had 699 misfires, with the next highest number being 19 (cylinder 2).
I also looked at the ECM’s code history, which revealed P0106 (map sensor pressure fault), P0300 (many misfires), and P050D (multiple misfires) (cold start rough idle).
I have never observed my coolant level dropping, and I change my oil on a regular basis, most recently last weekend, but my coolant has never seemed milky or smelled like coolant.
All that is left, after ruling out everything else, is a set of defective seals on injector 3 that is letting leak back at the first engine start, which is responsible for the misfires on cylinder 3.
There is simply a difficult cold start that occurs sporadically (and is becoming more common), but there are no other concerns.
What is the procedure for changing GDI fuel injectors?
The majority of my repairs and maintenance are completed by myself – with the exception of major work.
Is there a set of instructions or a how-to for doing this task?
Also, I’ve heard that if I replace any injectors, I may need to replace the fuel injector rails/lines as well, because the stainless steel is so soft that it may leak within a short period of time even if I simply replace the injectors themselves.
Do you have any thoughts about doing the task yourself? PS – I’ve checked YouTube and Google for ANY directions (including for other GDI engines) and have come up with nothing on how to bleed the fuel pressure, just videos on how to put on new injector gaskets, which is frustrating.

Chevy Silverado and GMC Sierra Starting Problems
This is my 2003 Silverado, and over the course of the last year and a half or so, it’s decided that it no longer wants to start at all. When I turn the key in the ignition, all of the lights and gauges, as well as the radio, come on, but the vehicle will not start. It does not make any clicking or anything like that, and I have taken it to the mechanic more times than I want to remember, and no one has been able to figure out what is wrong. So I took it to the mechanic, and of course, it began right away.
The starter has been tested and found to be in good working order; a new battery has been installed; wires have been tightened; relays have been replaced; and still the problem persists.
It may be anywhere from 5 minutes to an hour or more before it chooses to start, and I don’t want to be stuck for that long by myself.
THANKS!
Chevy Truck Cranks But Won’t Start (Silverado 2002, 2005, 2006, 2008, 2012, 2018)
If your Chevrolet vehicle just cranks but won’t start, there might be a number of issues causing the irritating situation. Because there are so many possible causes for your truck’s inability to start, you must employ a process of elimination to identify the underlying problem. But where does one even begin? If your Chevrolet vehicle cranks but won’t start, start by eliminating the most apparent culprits, such as a dead battery, a malfunctioning immobilizer, or a lack of petrol. Spark plugs, fuel injectors, compression and distributor troubles, as well as ignition coil issues, are all common problems with a chevrolet engine that won’t turn over.
To learn more about the most frequent underlying issues that might cause a problem and how to resolve them, please continue reading this article.
Quick Checklist for Starting Issues
Before proceeding to more significant difficulties, make certain that the problem is not a straightforward one that can be resolved immediately. These concerns may appear to be self-explanatory, but it is all too easy to mistake the most evident faults for those originating from a more technical source. Here’s a short check to make sure the most obvious cause for your Chevy engine not turning over has been ruled out.
- Check to see that you have enough fuel in your tank. Identify any error codes stored in the computer’s memory. Check to see that your car’s battery is completely operational. Check for problems with the starting motor or the circuit
- Check to see whether your truck’s immobilizer or wrong security settings are preventing it from starting. Examine the circuit for blown fuses.
See the video below for more information: Chevy GMC Engine Cranks But Won’t Start
You Have a Spark Plug Problem
When it comes to your Chevrolet Silverado’s ignition system, spark plugs are critical components. If your truck cranks but won’t start, one of the most likely causes is a defective spark plug. In your engine’s combustion chamber, your spark plugs are responsible for delivering electric current from its ignition system to the combustion chamber. The spark plug ignites the compressed fuel and air mixture given by the piston while preserving the engine’s combustion pressure by maintaining combustion pressure.
There are a variety of reasons why your spark plugs may be defective; beyond that, they may have reached the end of their useful life. However, additional indications of spark plug defects, such as the following, may be associated with the starting problem:
- Hard starts, engine misfires, and rough idling are all symptoms of increased gas usage.
Your spark plug has a lifespan of 30,000 to 120,000 miles, depending on the model and engine of your Chevrolet. The ignition coils and spark plug wires have a lifespan that is about twice that of the spark plugs. It is not difficult to replace a spark plug, but you may have to negotiate around shields and intake manifolds in order to get to them.
How to Solve Spark Plugs Issue?
A spark plug tester is a useful instrument that you can use to test your spark plug by placing it against your ignition wire while it is attached to your spark plug. As soon as you turn on your car’s ignition, look inside its clear sides for evidence of visual sparks or a glow, indicating that the ignition is firing. If your spark plugs are burning, you should see visible sparks or a glow even if the car doesn’t start.
By Eye
It is possible to perform a quick visual inspection by simply removing the spark plug from the engine. Connect the tester ignition wire to the terminal of the spark plug that has been removed, and then make a contact between the metal portion of your cylinder head and the lower metal part of your spark plug. Begin by turning on your engine and watching for the presence of a spark emitted from the spark plug tip.
Assess Your Spark Plugs
Once the spark plug has been removed, you may look for signs that you will need to replace it on the top of the spark plug. Your Chevrolet’s central electrode should have a light brown or grey residue, and it should not have visible traces of oil or black deposits that may interfere with the vehicle’s starting.
Replace the Spark Plug
To restart your engine, replace the spark plug with a new one of the same type and try to start it up again. You may want to rule out spark plugs as a possible source of your engine issue and move on to the next possible culprit if your Chevy truck continues to crank but not start after you have eliminated the spark plugs.
You Have a Fuel Supply Issue
Even when your engine is spinning at high RPMs, fuel injectors are responsible for delivering accurate quantities of gasoline to each cylinder. Gasoline injectors provide fuel to the combustion chambers of your truck’s engine to ensure optimal combustion and efficiency. It is estimated that the injectors fire millions of times over their lifetime, making them susceptible to wear and tear as well as blockage, which can cause your engine to malfunction. If the fuel in your Chevrolet is not getting to the cylinders, your vehicle will most likely crank but will not begin to run.
- The gasoline tank has been completely refilled. Your gasoline pump is in perfect functioning order
- Your filter is clear of clogs at this time. The fuel pressure regulator in your vehicle is operational. Fuel injectors are not clogged in your vehicle.
Spraying starting fluid into your air intake pipe is a quick and easy approach to check for fuel supply problems. If your Chevrolet runs for a few seconds before dying, this indicates that your Chevrolet is not receiving the proper quantity of gasoline.
How To Solve Fuel Injection Issues
It is necessary to have fuel injectors since they accurately measure the amount of gasoline that enters the intake manifold and your engine.
Alternatively, you may look out the appropriate resistance for your specific fuel injectors online or reference your vehicle’s maintenance manual. If your Chevrolet isn’t starting because of dirty or leaky fuel injectors, you should look for signs such as the following:
- A decrease in the performance of your truck
- You will see an increase in your gas bill as a result of higher fuel use.
If you want to troubleshoot fuel injection problems, you should use a multimeter to test each fuel injector individually. To get the right resistance for your specific fuel injectors, you may look them up online, review your car maintenance manual, or simply follow these steps:
- Remember to switch off your automobile before starting this test because you will not require any electricity for this one. Remove the injector wiring harness from the injector. Put your multimeter or Digital Volt-Ohmmeter on the ohms setting and check your results. By pacing the meter leads on the prongs within the connectors and making certain that they are not contacting one another, you may determine the resistance
- If you have high impedance injectors, you should anticipate a reading between 12-17 ohms, and if you have low impedance injectors, you should expect a reading between 2-5 ohms. Repeat the process on all of your injectors. There should not be a variation in resistance of more than half an ohm between the injectors, and any injector that produces a different reading should be investigated
Otherwise, it’s possible that the fault is with your wiring harness. Start your vehicle with the ignition turned on but not running, and check the DC voltage at each wire harness connector. If your readings for each of your injector wiring harnesses are less than 12 volts, it is possible that there is an issue with the wiring itself.
You Have a Compression Issue
When there is insufficient compression in the fuel/air mixture, the spark plugs are unable to effectively ignite the spark that ignites the combustion that is required to power your engine. There is a leak because the compression cannot maintain combustion, and your automobile will not operate if there is one. Typically, compression problems are caused by:
- Jumped timing belt
- Burned or damaged valves
- Worn-out compression rings
- Blown head gasket
- And other problems are possible.
Other signs that your Chevrolet truck’s timing belt is malfunctioning are as follows:
- Problems with your car’s engine revving
- Ticking noises from the engine
- Issues with exhaust, such as heavy smoke
How to Solve Compression Issues
Your timing belt/chain is responsible for ensuring that the camshaft and crankshaft rotate in the same direction. Timing belts have a limited lifespan and may get worn and damaged as a result of wear and tear. Because Chevy models differ, you should check your truck’s owner’s service manual to discover how often you should change the timing belt to guarantee that these problems do not arise. Because removing your timing cover will only partially disclose the workings of your timing belt on select Chevy models, your best resource is to reference your owner’s handbook to determine when it is time to replace the belt.
You Have Ignition Coil Problems or Distributor Issues
In most recent Chevrolets, there are no longer any distributors; instead, there is an unique self-contained plug wire with its own coil. A coil pack is a set of coils that are either attached to the plug by this updated version or may be found separately in a coil pack. Here are a few troubleshooting suggestions for your distributor or ignition coil that you might find useful:
- When in operation, your ignition coil should provide a clean spark, indicating that the coil is not the source of the problem. As a result of this information, it is likely that your distributor, as well as the wires connecting your coil, plugs, and distributor, are at issue
- If there is no spark, you must investigate the coil itself or its interconnected wires to determine the source of the problem. Check that your ignition coil has the proper voltage, and if it does not, trace it back to see if there are any disconnections or interference. Check to see whether your crankshaft position sensor is functioning properly (if relevant).

Hopefully, it is something basic that you can handle on your own, but if it is anything more severe, it is advisable to seek expert aid. Keep an eye on the recommended replacement intervals for your Chevy parts, and you will go a long way toward avoiding future issues. References
2007 Silverado 1500 No start/no crank, relay is good, starter is good, battery is good
QuestionsAskedViewed801 times Despite the fact that I am not an expert, I can typically pinball my way through most projects with the help of a few YouTube videos and online research. The other day I went out to determine why I was not receiving electricity for the right trailer turn signal at the receptacle on the bumper, as I had done in the past. This was intended to be a simple job, but I made a few mistakes and could have sworn I checked all of the fuses, but in the end, it was only a blown fuse that was the problem.
After reconnecting everything, I attempted to start the truck and discovered that all of the interior lights/functions, such as the radio, air conditioning, and so on, were activated, but that when you turned the key further to crank it, nothing happened; keep in mind that the truck had been running fine the day before.
- When the key is turned, the starting relay makes a clicking sound.
- Because I created a jumper connection from a little piece of wire to bypass the starting relay, I know the starter is in fine working order as well.
- As a result of my tinkering with the other issue and making/breaking all those electrical connections, I have to suppose that something has been dampened or provoked to fail; yet, I have thoroughly investigated everything and cannot see anything visually out of order.
- However, the vehicle would not start despite my efforts.
- Please let me know if you have any advice or recommendations, which I would really appreciate.
asked Oct. 6, 2019, 7:144 a.m. After confirming that all fuses are operational and that no pins or wires have been damaged over the process of your blinker diagnostic, we’ll start with the basics and work our way up from there.
- You said that your dash lights are working while the key is in the on position, which is a good indicator. Do you hear the priming of the fuel pump as well? Are there any red or yellow ‘Security’ indicators on the dashboard, if not, where do you see them? If this is the case, the anti-theft security system may be able to disable your truck. Even if the pump is primed, the immobilizer will prevent ignition signals from reaching the PCB and causing it to malfunction. In my investigation, I discovered that doing the security reset method is effective 50% of the time.
I. Keep the key in the ‘On’ position for roughly 10-12 minutes, or until the ‘Security’ indicator vanishes completely. II. Hold down the key in the off position for 20 seconds. III. Repeat steps one and two as many times as necessary. Removing the key and attempting to lock and unlock doors with the fobV. Start the car by inserting the key and pressing the start button.
- Disconnect both battery terminals and press them together for 10 minutes to release the tension (zip-tie). As a result, everything in the system will be discharged, and the security system will theoretically be reset. The results of this appear to be restricted
- Go through as much of the wiring as you possibly can in search of problems. Corrosion on the PCB might be a problem depending on your geographical location.
I will continue to improve this document when new facts and ideas become available. If someone can come up with a viable solution, I will remove this post. answered Oct. 6, 2019, 11:565 a.m.

Hello, this is my first time posting here. I have a 2003 2500HD crew cab 4×4 extended bed that I tried to start a couple of weeks ago after it had been sitting for a week. The truck cranked well, but wouldn’t start. When I released the key, there was no crank. I saw that the fuel gauge and, I believe, the volt gauge were not functioning properly. I tried leaping and it did the same thing. Disconnected the battery cables, cleaned them, and reassembled them. Turned the key in the ignition, the gas gauge read correctly, and the car started right up.
- When I tried it a second time, it would not crank over.
- When I got into the car, the gas gauge functioned and it started straight away.
- Allowing it to sit overnight had the same results: the gas gauge would not function, and the engine would not start.
- Thinking it was a fuel pump/sender issue, I removed the pump relay and tested the fuel pressure, which was approximately 60 psi.
- The connections on the PCM were similarly clean and bright when they were pulled.
- This morning I tried it again, and it wouldn’t start since there was no gas gauge.

3.0L Duramax diesel has known long crank start issues, but no recall – Pickup Truck +SUV Talk
Various owners of General Motors trucks and SUVs equipped with 3.0-liter Duramax Diesel engines may be interested in following some forums or YouTube channels where they are discussing the Duramax diesel long crank start or no-start difficulties that have been observed on some of these engines. Tim Esterdahl, the publisher, receives a lot of mails concerning this, so he felt it was time to sit down, do some research, and put together a film on the subject.
Which GM vehicles are affected?
At first sight, it appears that any vehicle equipped with a 3.0-liter Duramax diesel engine — including the Chevrolet Silverado, Chevrolet Sierra, Chevrolet Suburban, Chevrolet Tahoe, Chevrolet Yukon, and Cadillac Escalade — may have crank start difficulties, including extended crank times or no start.
And by that, we mean the light-duty trucks and SUVs that General Motors has produced in the previous three years – particularly, the models from 2019, 2020, and 2021.
The 3.0L Duramax diesel long-crank culprit
Many people are wondering why there hasn’t been a recall if this is a well-known problem (which it is). The reason for this is because, despite the fact that the lengthy crank or no-crank has been documented by several owners and dealership personnel, the underlying cause is not always the same. There is no way to just say, ‘Oh, this is the problem,’ and then correct it for everyone when you have a huge list of potential culprits to choose from. The most common cause of camshaft wheel failure has been identified as a bent or warped camshaft wheel, according to forums, message boards, and YouTube videos.
Alternatively, the engine may fail to start at all.
Why hasn’t the part been changed if it’s a faulty component?
It’s possible that a defective supply batch is to blame, but determining the exact reason is difficult when the problem is so sporadic and the cause isn’t always the same.
Replacing the wheel isn’t alway the fix
Truck owners have reported a number of possible causes, all of which, when addressed, have resolved the lengthy cranking difficulties with their 3.0-liter Duramax diesel engines. A bad wire harness, a newly updated ECU, a camshaft position exciter wheel, fuse boxes that require torqueing, malfunctioning actuators, and faulty fuel pumps are examples of what might go wrong. A lot of dealer mechanics will start with the easy things and work their way up the chain, which means your truck may be in and out of the dealership many times while they troubleshoot and, hopefully, repair the situation.
What are your thoughts?
Note from the editor: Since the publication of this article, General Motors has suspended, but not ceased, the manufacturing of this engine.
Is it possible that this problem will be resolved when production resumes?
- Production of the 3.0L Duramax diesel engine by General Motors has been paused, not discontinued. Is there a problem in the design of the Chevrolet 3.0L Duramax diesel? MPG when towing with the 2020 GMC Sierra 3.0L Duramax Diesel
- The Duramax engine in the 2021 Chevrolet Silverado 1500 is subject to modification.
Immobilizer Intermittent? Engine Not Cranking Over?: I Have a 2018.
I have a 2018 Chevrolet Silverado Z71 4×4 pickup truck. When I switch off the ignition, the engine will not start for up to 10 minutes, which happens occasionally. Despite the fact that the engine will not crank, all of the dashboard lights, including the security light, will illuminate and operate as normal. Before or after I switch off the ignition, there are no warning lights or sirens to alert me to anything. After ten minutes, the engine begins to crank and start like it should. During the 10-minute window, remote start is not available.
I’ve taken it to two different dealers, and both have stated that there are no fault codes, that they were unable to reproduce the no crank scenario, and that the system is functioning properly.
That is not the issue.
This is also not an issue. It’s now doing it occasionally everywhere I go, not only in my driveway anymore. IS THIS A SPONSORED LINKDo you have the same difficulty as I do? Yes No, on Friday, January 25th, 2019 at 10:51 a.m., the answer is no.

Common Symptoms Of A Bad Fuel Pump
When a gasoline pump fails, it will usually do so in one of two ways. It will either cease operating altogether (generating no fuel pressure) or produce an engine no-start problem if it continues to work. Alternatively, the gasoline pump may begin to fail and will only operate well enough to start the car, but the engine will not run at its peak efficiency any more. This means that the gasoline pump only provides enough fuel pressure to start the engine, not enough to propel the car along a highway.
- The engine turns over but does not begin to run. A few seconds after starting, the engine fails to operate properly. After starting the engine, the engine stops as soon as you press your foot on the accelerator pedal. Inability to drive the car due to a lack of power
- When you step on the accelerator when the engine is under load, you can hear explosions coming from the intake manifold. In addition, lean air fuel mixture fault codes have been saved in the memory of the fuel injection computer
- The check engine light is illuminated.
Where To Buy A Fuel Pressure Test Gauge
A fuel pressure test gauge can be purchased almost anyplace, and it is one of the most crucial instruments that every serious DIYer should have in his or her tool collection. The Actron CP7838 Professional Fuel Pressure Tester is the fuel pressure gauge kit that will attach to the Schrader valve on your Chevrolet or GMC pickup or SUV, and it is my top recommendation because of its inexpensive price and long service life. Fuel pressure test gauge kits for your Chevrolet Silverado (Suburban, Tahoe) and GMC Sierra (Yukon, Yukon XL) are available in a variety of configurations.
TEST 1:Testing The Fuel Pressure With A Fuel Pressure Test Gauge
As I indicated at the outset, testing the fuel pump is as simple as attaching the fuel pressure test gauge to the fuel system and turning on the engine. The Schrader valve, which is placed on the fuel injector rail, is connected to the fuel pressure test gauge (passenger side of the intake manifold). Please keep in mind that if you don’t already have a fuel pressure tester, you may get one at your local auto parts store. Alternatively, you may look at my recommendations for where to get a fuel pressure test gauge here: Where To Buy A Fuel Pressure Test Gauge to save some money.
Engines that run on flex fuel have a PSI of 48-54.
- 1Connect your fuel pressure tester to the Schrader valve
- 2ask your assistant to crank the engine while you keep an eye on the needle on the fuel pressure tester gauge
- 3ask your assistant to turn off the engine while you keep an eye on the needle on the fuel pressure tester gauge
- The gasoline pressure tester should give you a number between 55 and 62 PSI
- Otherwise, proceed with caution.
Let’s have a look at your test results: CASE 1: The fuel pressure is within the range of the specified specifications. In this case, the test result is correct, and it informs you that the fuel pump in your V8 Chevrolet Silverado (Suburban, Tahoe) and GMC Sierra is functioning properly (Yukon, Yukon XL). CASE 2: You have a fuel pressure of 0 psi. This test result informs you that the fuel pump is faulty and that the engine is unable to start as a result. Before replacing the fuel pump, check to see that the fuel pump relay and fuel pump fuse are both providing power to the fuel pump when the engine is started.
IN CASE 3: The fuel pressure was lower than the specified fuel pressure range.
This test result informs you that, despite the fact that the fuel pump is supplying some gasoline, it is not supplying enough to allow the engine to operate at peak performance. This is a sign that the gasoline pump is failing and that it is necessary to replace the pump.
