- If you own either a Dodge or Plymouth Neon and experience a no start or stall condition, you may have a shorted vehicle speed sensor (VSS). The VSS shares the same power circuit as the crankshaft position sensor (CKP) and camshaft position sensor (CMP). The most common way for the VSS to short is power to ground.
Why is my Dodge Neon not starting?
The most common reasons a Dodge Neon won’t start are a dead battery, an alternator problem, or failed starter.
Why does my Dodge Neon idle rough?
The most common reasons a Dodge Neon has rough idle are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil.
Where is the fuel filter on a 2004 Dodge Neon?
The fuel filter is located in the fuel tank and is not seen by Dodge as being a service item.
How do you fix a surging idle?
Start the engine, then increase and hold the idle speed to 1,000 to 1,500 rpm. Turn the engine off to allow the cleaner to soak into the IAC passageway. Restart the engine, rev and hold at 1,000 to 1,500 rpm, and repeat the cleaning process again.
Where is the fuel filter on a 2002 Dodge Neon?
The fuel filter is always going to be found between the fuel tank and the engine. For most vehicles, the fuel filter is located inside the top of the fuel tank, right where it connects with the fuel line, although on some cars if might be elsewhere along the fuel line.
What causes an engine to surge while idling?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
What causes engine to idle up and down?
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
Why is my car revving up and down?
Car Revs Up and Down Causes Transmission fluid is exclusive to automatic vehicles. As you speed up, this fluid starts to flow faster, lubricating different parts as it moves along. Any kind of leak in the line will make your car start to pick up RPMs, making it rev up as your driving.
Dodge Neon won’t start and stalls
A shorted vehicle speed sensor may be to blame if you own a Dodge or Plymouth Neon and your vehicle won’t start or stalls while driving (VSS). In addition to the crankshaft position sensor (CKP) and the camshaft position sensor, the VSS is powered by the same power circuit (CMP). The most typical way for the VSS to short is to connect the electricity to the ground terminal. The CKP and CMP are unable to receive electricity as a result of this. Locate the VSS on the transmission extension housing and do the test there.
At the very least, you should observe 7 volts.
Start the engine if you are now getting 8 volts.
Intermittent stalling can also be caused by a malfunctioning VSS.
You won’t be able to see your speedometer reading.
Replace the VSS with a new one.

Number one rule in this case is to keep things simple, dumb. To put it another way, always start with the simple stuff and work your way up to the difficult stuff. Please keep in mind that all of these tests are short checks that we are trained to perform using a volt meter and an amp clamp, and they are essentially the same tests that are found in the 1995, 1996, and 1997-99 model year factory service manuals. Because the FSM assumes you have a battery charger as well as a load tester/charging system tester, these are not the precise processes you should follow.
- This is the root cause of 75% of all battery failures; it will result in a dead battery and may even have enough resistance to prevent you from starting your car.
- It should have the appearance of a fisheye lens.
- Put your volt meter over the terminals of your automobile while it is still running.
- You should have a voltage readout of 13.75-14.25 volts, or anything very close to that.
- If you don’t display 13.75-14.25, you’re almost certain to have an issue.
- If you connect one end of your digital voltage meter to the nut on the rear of the alternator that holds a long wire, you’ll get an output signal.
- Start the engine of the automobile.
This is done in order to measure the voltage drop in the + circuit.
This is the voltage differential between the two ends of the cable, and it serves as an indicator of the cable’s condition.
Now we’re going to look for voltage drop on the ground side of the connection.
If you notice more than 0.3 volts on this one, you have a problem.
If your reading exceeds the limit on either of these, locate the source of the problem by checking each connection, starting at the battery and working your way down the line, until you isolate the bad wire, which you should then replace.
Everyone should be aware of this information.
If you pass those tests, you’ll go on to the battery testing stage.
This is the only technique to accurately determine the state of charge of a battery.
You can pick one up for a few dollars at napa or maybe even autozone if you look around.
To begin, ensure that your water reservoir is completely filled, then follow the recommendations and always wear gloves and safety glasses.
For those who have gotten some on themselves, sprinkle some baking soda on them and then rinse them thoroughly.
Due to the fact that baking soda is a base, and a base will neutralize an acid, this is true.
Unplug the coil pack so that your vehicle will not start.
I’m talking about everything.
(If it’s chilly outdoors, you may obtain lower readings, but they should be no lower than 8.8 and that’s if the temperature is below zero degrees Fahrenheit inside.) If your battery’s voltage is low, it means that it is either not charged or that it has one or more shorted cells.
It is quite detrimental to the battery.
If your battery fails the hydrometer or the load test, the next step is to replace it.
You’ll need a digital volt meter for this one, as well as a battery charger with a 40 amp capacity.
You MUST NOT do this test on a maintenance-free battery, as this will result in damage.
As a result, you must remove the caps that cover the cells, just as you would if you were adding water to the electrolyte.
Also, don’t smoke, since there’s nothing worse than the smell of burning hydrogen and flying battery acid.
You have been warned, and please do not hold it against me if your girlfriend dumps you because you appear to be the joker.
If your battery voltage rises beyond 15.5 volts, it is almost probably damaged.
If I had the financial means to do so, I would.
If you believe I should elaborate or express things in a different way, please let me know.

Dodge Neon Dies After Starting Diagnosis
The fact that your Dodge Neon keeps starting and then shutting off might be quite unsettling. It is most likely caused by some form of malfunction in the electrical or fuel systems of the vehicle. However, there may be more factors at play. For your Neon’s engine to function properly, it requires three items to be present at all times and in the appropriate proportions. If your car starts up, but then quickly shuts down, it may be receiving all three at first, but something is definitely preventing it from receiving all three on a constant basis, as described above.
- When you press the beginning button, the engine begins to turn gently.
- At this point, the starter is no longer engaged, and the car will require a steady supply of fuel to function properly.
- When a car starts but subsequently dies, this is one of the most prevalent explanations for the problem.
- Before beginning any manual diagnostic, it is recommended that you check for OBD2 codes on the vehicle.
Causes:Neon Dies After Starting
Following are only a few of the most prevalent reasons why your Neon begins to run but suddenly stops:
1. Lack of Fuel Pressure
Modern fuel-injected engines require a significant amount of fuel pressure to function properly. Unless they are supplied with sufficient pressure, they will not function effectively. There are a few possible reasons why you may not have adequate fuel pressure in your vehicle. It’s possible that the gasoline pump is faulty. When the engine is first started, the fuel pump may be able to provide sufficient fuel pressure, but it may not be able to maintain sufficient pressure to keep the engine running.
- However, most engines are equipped with a port that allows you to check the fuel pressure using a gauge that you can either rent or purchase from a store such as Autozone or other such establishment.
- Now is the time to start the engine.
- Is it possible to travel all the way to zero?
- If the fuel pressure goes below a certain level and the engine shuts down, but then the pressure rises again, the problem is most likely a malfunctioning fuel pump or fuel filter.
In order to verify whether the fuel pump relay is receiving continuous voltage, an expert mechanic with a decent scanner must first check the voltage at the fuel pump relay.
2. Lack of Spark
In order to stay operating, today’s fuel-injected engines require a significant amount of fuel pressure. They will not function correctly if they do not have sufficient pressure. If you do not have adequate fuel pressure, there are a few possible causes. An issue with the fuel pump might be present. When the engine is first started, the fuel pump may be able to provide sufficient fuel pressure, but it may not be able to keep the engine running continuously. It is possible to locate the fuel pump in the gas tank.
- As soon as you turn the ignition switch to the on position, take note of the gasoline pressure in the car.
- Are there any signs of a decline in fuel pressure right away?
- Typically, if it lowers all the way to zero and doesn’t come back, the fuel pump relay is to blame.
- If the fuel pressure returns to normal levels, the problem is most likely due to a faulty fuel pump or fuel filter.
3. MAF Sensor
The mass airflow sensor, often known as the ‘MAF’ sensor, measures the amount of air that enters the engine of your Neon. It’s located between the air filter and the throttle body on the vehicle. It is one of the most critical components that the vehicle employs to determine the proper air/fuel mixture for the driving conditions. It is well known that if it is not correctly calibrated, it will cause the automobile to not begin to start. Make sure that the wire harness surrounding it is properly connected and that it is firmly inserted in place.
An in-depth article on how to identify a malfunctioning mass airflow sensor may be found here.
4. Ignition Issue
Depending on how you start your Neon, it’s possible that the vehicle’s systems are only activated when you press the starter button. This is a problem that occurs when the ignition lock has become worn out and cannot be used. Essentially, when the key is turned on, the car is just ordered to ‘be on,’ and when the key is turned off, all systems are turned off. There are a few things you may perform to determine if this is the source of the problem with your vehicle. If you happen to have a different key, you might try starting it with that one.
Take a look at the warning lights on the dashboard if you don’t have a spare key with you.
Alternatively, if they only come up when you first start the car, it is possible that you require a replacement ignition switch. Do not rely on the radio, windows, or power seats to notify you whether or not the car is running. A lot of the time, they’re on a separate circuit.
If there are any fault codes present, the first thing that you should do is connect a decent code scanner to your vehicle and check it out. These can be quite useful in illuminating what is happening with the car. These are some of the most typical reasons for a failure to diagnose if nothing is found throughout the investigation. Alternatively, taking it to a reputable store may be the best option. It might be tough to figure out what is wrong with a car that stops immediately after starting.

Dodge Neon Questions – Periodically won’t start and now.
In the course of a single year, my neon decided that it no longer wanted to start on occasion. I’ve now discovered that it occurs most frequently after a day or two of sitting when the temperature rises beyond 80 degrees Fahrenheit and then begins to decrease. If I drive it on Tuesday and don’t touch it again until after 5 p.m. on Wednesday, and it has gotten warm enough, it will struggle to turn on at the end of the day on Wednesday. No sound indicates that it is having difficulty getting started, but rather that it should be starting just fine but stalls out instead.
- I end up bicycling or getting a cab to get the last 10% of the way.
- I did the spark plug replacement myself at a fraction of the cost.
- They are now at a loss (particularly considering that it has always started off perfectly for them).
- I’m experiencing issues with the fuel injectors in my car right now, and I have to put fuel injector cleaning into the tank every few months or I’ll get a check engine light and some harsh driving conditions.
- I’ve just crossed the 100,000-mile mark.
Chrysler Neon Stalls: causes and solutions
Chrysler Neon, model year 1998, with 155,000 kilometers. Hello and good morning to everyone. My Neon 98 has just began stalling out in the middle of a highway drive. What I need to do is to separate the positive wire from the battery and reconnect it to the battery terminals.
That is the only way I have discovered to get it to start; otherwise, it flashes but never gets it to turn on. What could possibly be going on? Is it possible that the computer is malfunctioning and has to be reset? If you could assist me in any way, I would be really grateful. Thanks.
The car stalls out at half a tank of gas
Vehicle: Chrysler Neon, year: 1998, mileage: 150000 All of you should have a good morning! Driving my Neon 98, I’ve noticed that it has been stalling unexpectedly lately. What I need to do is to unhook the positive wire from the battery and reconnect it to the battery terminals again. Otherwise, it flashes but does not start, and I have discovered no other method to get it to turn over successfully. Can you tell me what’s going on here? Is it possible that the computer is failing and that it has to be rebooted.

Cranks but wont run.
Chrysler Neon 2005 2.0 with 222483 kilometers on the clock The engine starts OK, but after about 20 seconds, it shuts down as if it ran out of gas. I replaced the fuel pump twice, then the crankshaft sensor, the camshaft sensor, and the idle position sensor, but the problem persisted. I took it to the Dodge dealership, where they determined that it needed a pcm. We installed a new one, but the problem persisted. Every time, it starts off strong then fades after approximately 20 seconds. Is there anyone who could assist us with this problem?

1998 Chrysler Neon with 3000 miles on it I’m in need of assistance with my Neon 98. The positive terminal of the battery made touch with the bonnet of the automobile a few days ago, causing the vehicle to stop. Since that time, it has been unable to start the engine at any time. The lights do not illuminate, neither the electronic windows nor the windshield wipers operate, and there is no spark produced by either the spark plugs or the injectors in the vehicle. I’d want to know if the problem is with the computer or if there is a blown fuse or a broken sensor in the vehicle.

Acts like it’s bad gas at 1/2 a tank
Chrysler Neon 1999, 4 door, 5 speed manual transmission At half a tank of gas, 2.0 is a good number. It stalls out like a car with poor gas. 144000 kilometers = 144000 miles It acts as though it is about to die and will barely move even with only half a tank of petrol in the tank. There’s also another issue to consider. It does not have a 5th gear at all. He recently bought this automobile, and the person scammed him off by promising to make sure everything was fixed, and now he won’t answer either of our calls or respond to our emails.
