Hard start when cold Ford? (Correct answer)

Most common cause of hard start when cold Let the vehicle cool until the engine is cold. Then perform a cold start test. If you encounter the same hard start when cold and the FLEX FUEL DATA reading is back up to 70% or more, your next step is to check fuel pressure.

  • If you have a Ford vehicle and find that has a hard start when cold condition, here are the common things to check. The issue appears as an engine that will crank but has a hard time firing up. Once it does start, it doesn’t run well. It may run extremely rich, which you will notice with rough idle and poor MPG.

What causes hard starting engine when cold?

Cold batteries simply don’t produce the same amount of power as warm batteries, and this effect can lead to starting issues. When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. If the battery is already low on power, this can result in a non-starter.

What would cause a Ford truck not to start?

If the battery alternator and the charging system check out, another reason would be a failing starter, the internal windings could be binding. There could also be an issue with the fuel delivery system, a bad fuel pump clogged filter or fuel injection issue.

What is a cold start engine?

When your car’s engine is colder than its normal operating temperature and you start it, that’s a cold start. That means that every time you start your car after it sits for a long period of time, you are having a significant impact on the air quality.

How does a cold start work?

To start with, a car’s ECU decides that the engine has to idle higher when the engine is cold to stop it from stalling. This is programmed into the ECU via a start-up map, which allows a richer air/fuel mixture to enter the cylinders.

Can a bad starter cause hard starting?

Bad Starter Bad starter is one of the reasons causing car having trouble starting that you cannot avoid. At one time or another, the starter motors will wear out and suffer a breakdown.

How do I know if my starter is bad on my f150?

Symptoms of a Bad Starter on a Ford Truck

  1. Click. When the ignition key is turned to the start position and nothing occurs except a rather loud and heavy-sounding click noise, the starter may be seized up.
  2. Motor Without Engine. The gear in the nose of a starter is known as a bendix.
  3. Grind Aftershock.
  4. Lock Up.

How do you know if your starter bad?

Something sounds off. One of the symptoms of a bad starter is a clicking noise when you turn the key or push the start button. However, a starter can die without making any sound at all, or it may announce its impending death with whirring and grinding noise—so listen up!

Why is my Ford f150 not turning over?

The most common reasons a Ford F-150 won’t start are a dead battery, an alternator problem, or failed starter.

Is it bad to start car in cold?

Warming Up Modern Day Vehicles That means the engine should be ready to go as soon as it begins running. So by idling your car, you’re just releasing extra gas into your engine without getting any use out of it. So if you consistently get started too soon in the cold, you could eventually end up harming your engine.

What happens if engine runs too cold?

If you run your engine cold all the time, you’ll most likely experience increased fuel consumption across the board. Additionally, you’ll find higher amounts of carbon buildup at various parts of the engine. The most damaging effect of feeding a fuel-rich mixture to the engine is excess fuel reaching the exhaust.

How cold is too cold to start your car?

If your car gets extremely cold, the battery could freeze. Now, the good news is that it must get extremely cold before that happens. Some experts suggest as cold as negative 76 degrees. That said, even at 32 degrees, your battery can start having problems.

Why do cars rev higher when cold?

Gasoline vaporizes much more easily in warmer temperatures to get that spark. In colder temperatures, fuel is more likely to get bogged down and thicken. Therefore, the vehicle overcompensates for this by producing a higher RPM initially to move gasoline more quickly.

What causes rough idle when cold?

While there are many potential causes for shaky cold-weather performance, two of the most common are failing engine temperature sensors and bad thermostats. In both cases, the underlying reason for a rough idle is an overly rich air to fuel mixture.

Ford Fiesta: Won’t Start When Cold → Diagnosis

Extreme weather conditions may make driving your Ford Fiesta extremely challenging. If there is a problem, it will usually become apparent when things are at their worst. When the weather is exceedingly hot. The cooling system is put to the test in this situation. When it is chilly outside in the winter, the vehicle will not start. There are a variety of factors that might contribute to this, but the most common is that your Fiesta’s battery is unable to cope with the demands of starting the car when it is cold.

It’s possible that the chilly weather is preventing your Fiesta from getting started. However, you don’t want to discount out the possibility that it’s just not starting because it’s chilly. If this appears to be a problem for you, visit Ford Fiesta Not Starting for more information.

Ford Fiesta:Won’t Start Cold – Causes

The battery is by far and away the most common cause for your Fiesta not to start when it’s chilly outside. Cranking amps and cold cranking amps are two different types of ratings for batteries. Cold cranking amps are a measure of a battery’s ability to start and turn the engine over when the battery is completely charged. The capacity of a battery decreases through time and use. As a result, it may have sufficient cranking capacity to start the car while it is warm, but when it is cold, it simply does not have the capacity to turn the engine over.

2. Wrong Battery

If you purchased a battery during a period of warm weather and your Fiesta won’t start after less than a year, it’s possible that you got a battery that lacks the cold cranking capability that your vehicle need to begin operating properly. This is frequently the case when you have a six-cylinder vehicle and receive a battery designed for a four-cylinder vehicle. The capacity to turn over a larger motor when it is really cold is not quite sufficient for this application. The most common cause for your Fiesta not to start in cold weather is a drained or dead battery.

3. Wrong Oil Viscosity

If you use a thicker oil in your Fiesta during the warmer months, it will be less likely to prevent it from starting. However, it will make itself known throughout the winter. The larger molecules in the thicker oil might prevent the engine from spinning over quickly enough to start the vehicle. For example, you could have purchased 10W-30 when the manufacturer had specified 5W-30 instead.

4. Water in Fuel Line

When the temperature of the surrounding environment changes, condensation can form in the gas tank. If the moisture makes its way into the fuel line of your Ford Fiesta, it might cause the engine to become unable to turn over due to freezing. This is a distinct possibility if the engine is starting quickly and it appears that the battery is in good condition.

How to Start Your Fiesta in the Cold

Here are some tried and true methods for starting your automobile while it’s freezing outside. You may use them to troubleshoot a car that you may be sitting in right now, and they are provided in the sequence that will assist you get moving as soon as possible. They are not presented in any particular order. A battery-related problem will be the most common, and that is what we are concentrating our efforts on right now.

1. Turn on All of the Accessories and Lights

Considering that the battery isn’t performing well to begin with, this may appear to be paradoxical. Essentially, what you’re attempting to do is give your Fiesta’s battery a brief period of “waking up.” As soon as you’ve completed this step, turn the key to the “on” position, but do not begin driving for at least 10 seconds. This allows the fuel pump plenty of time to prime the injectors before starting the vehicle. Now, go ahead and try turning the engine over to see if it will start on its own.

2. Warm the Battery

The battery can be removed from the vehicle if you are at home and are not in a hurry to get anywhere.

This will allow it to heat up to a temperature that will cause the electrons in it to begin to move. Allow it to sit for a few hours indoors. This can be really beneficial in getting the automobile to crank over. Handling the battery should be done with caution.

3. Jump Start

Jumping the Fiesta will get it back on the road in no time at all. Jump starting is the process of using the electricity from another car’s battery and alternator to charge your battery and assist you in getting your vehicle started straight away. Keep the engine from cooling down completely, since it will most likely not start on its own until the weather outdoors becomes warm enough.

4. Replace the Battery

You may take the battery to a nearby parts store and have it tested there as well. It would be good to do so before completely replacing it. For your specific Fiesta’s engine and model year, you should look up the cold cranking requirement for that vehicle. You want a battery that is capable of withstanding at the very least what the manufacturer suggests. Cold-cranking amplifiers are a commonplace. In order to achieve this requirement, a battery must spin for 30 seconds at 0° with a minimum voltage.

Conclusion:Fiesta Won’t Start in the Cold

Any of the battery-related concerns listed above might be the cause of your Ford Fiesta’s inability to start, which indicates that the battery should be replaced. If the weather heats up again outside, you may be able to get a few more decent starts out of it, but its time is running short.

Here in Missouri, the weather has been very chilly lately. When I get up in the morning, my truck has an issue with the transmission. Whenever I initially get out of bed in the morning to start my vehicle, it behaves and sounds like it is going to start right away. However, as soon as I release the truck key to disengage the starter, the truck will expire after a few of seconds of being released from the key ring. Sometimes all it takes is another turn of the key to get it going again, but recently it’s been taking two or three turns to get her going.

Hard Start when cold 2.5L

Even though the ECT sensor is not expensive to repair, a high cold idle and a moderate decline during warm-up would signal to me that it is functioning properly when this occurs. However, this might be sporadic at certain temperatures. Disconnect one coil pack and start the engine while it is still warm, making sure there aren’t any misfires. Whether one or more spark plugs are not working, you will know if there is a misfire if you plug in that coil pack and disconnect the other one. Because both spark plugs fire at the same time, 1995 and up 2.3l/2.5l engines are possible.

  • When was the last time spark plugs were changed, and what gap was used?
  • When it comes to fuel pressure, you can try turning the key on and off three times before attempting to start the engine to see if it helps.
  • You should have a three-port gasoline filter installed.
  • With the key off, a check valve or an FPR can cause a loss of pressure, but I would anticipate a decrease to zero psi.

Ford F-150 Questions – Hard start when block is cold

At 6:37 p.m. on September 10, 2015, 838840 Is there an engine light on in your vehicle when it is running? If this is the case, it would be wise to obtain some codes and see if we can narrow down our problem! Is your temperature gauge in proper working order? My best assumption is that it has something to do with a sensor that measures temperature, such as a coolant temperature sensor or an air intake temperature sensor, because it appears to be temperature related because it runs well when warmed up.

Hard to start from cold

I took a 2003 Ford Focus 1800 TDCI Duratorq in for service since it was having trouble starting from cold. It would start perfectly every time after it was warmed up. There are no DTCs stored, and live data shows that pressure generation is good. Checking the amps on the injector harness also indicated that the injection process had begun. Despite the fact that glow plug failures are not often connected with cold start troubles on current common rail systems, the fault displayed exactly the same symptoms as a broken glow plug as you would see on a direct injection configuration in this situation.

  1. Sure enough, they were all excellent, and I was starting to run out of ideas.
  2. Cranking speed is an important factor in achieving a successful cold start.

The 15th of January, 2013 My tdci was having the same issues as yours, and I was scratching my brain until I read your possible cause.

Thank you so much for your assistance.

13th of September, 2011 After recently experiencing the dreaded ‘click’ on my 2001 TDCI while twisting the ignition key, I noticed that putting the car into third gear caused the starter to activate as an emergency measure.

After considerable procrastination and the problem becoming worse, i.e.

Aside from the brushes’ ends needing a good clean, as well as the commutator and a sticky brush that needed to be freed, everything appeared to be in fine working order.

The feared ‘click’ might still be heard sometimes.

The only thing that might cause this is a shortage of current.

After thoroughly dismantling the faulty solenoid, I discovered that the situation was exactly as I had predicted.

Their corrosion causes them to produce progressively poor mechanical and electrical contact, which in this instance implies that even with a decent battery, the starter will turn more slowly; that is, if it would turn in the first place.

The ‘contacts’ on the solenoid are really the terminals on the solenoid to which the cables are linked; one cable connects to the battery, and the other to the motor; the solenoid has two terminals.

In order to carry the battery current over a copper strip on the end of the solenoid when it is triggered, the heads of the bolts are employed as contact points for the contacts (by turning the ignition key).

When a solenoid is used thousands of times, the heads of the bolts / contacts erode in a similar manner to how a welder works: metal is removed from one surface and deposited on another.

A consequence of the solenoid’s operating tolerances is that when the bolt heads / contacts corrode and degrade, they make less and less contact with the solenoid’s copper strip.

So if the headlights, horn, and other accessories operate properly, the problem is not with the battery.

Motors and brushes will outlive any relay / set of contacts that is ever created or used.

Giving the starting motor / solenoid a brisk tap (don’t savage it!) can generally jolt the solenoid connections and allow you to get back on the road in an emergency situation.

Getting to the starters these days is difficult, whether it’s from under the bonnet or by groveling beneath the vehicle.

Insist on having it replaced with a BRAND NEW one instead.

AndyB 14th of December, 2010 I was a little late in getting this done, but the new starter has made a significant impact – the car was nearly hard to start with the old started now that it is so cold – and the new starter has made all the difference.

In the event of a DMF failure, I would recommend that the starting be reconditioned.

I just replaced out my starter this morning and it started up on the first try.


AndyBOctober 12 2010I have precisely this problem – thank you for pointing me in the direction of a fresh line of research.

a sluggish start On this model, failed DMF appear to be fairly prevalent.

The 6th of September, 2010 Hello, Sutherml.

I’m not confident that my response will be satisfactory.

Over the course of its operational life, all of the mechanical components that go into its creation are destined to suffer some degree of deterioration.

Because of this, the brushescommutator would most likely lose part of their capacity to effectively carry current across the system.

It should also be recognized that the replacement unit may have been subjected to change, and may have been higher rated for the work in question.

Manufacturers respond by altering the specs of the components they use.

I hope this has helped to clarify my thinking.

What caused the starting motor to malfunction?

The 21st of February, 2010 Dave Where did you get the parameters for the starter, such as peak amp draw and amperage draw for each make and model of vehicle?

Continue your excellent effort, and once again, thank you.

A year ago, I was experiencing the same issue.

The sleeve of the starting motor was in poor condition.

The dust originated from the dual mass flywheel, which was a problem.

The 25th of May, 2009 My previous experience with a starting motor problem cost me £60 to have it diagnosed by a Ford dealer, which verifies your information above.

I replaced the motor on my Focus 1.8TDCI by myself, which took around 1.5 hours.

arman The 6th of March, 2009 hello there, Dave I work as a Lexus mechanic, so thank you for the helpful technical knowledge.

My brute force approach is what I enjoy.

In comparison to the 6.5, it ensures that the engine cranks smoothly and quickly.

The only negative aspect that I can see is that it appears to be a little harsh on glow plugs.

The 29th of January, 2009 Despite the fact that it may sound absurd, I am confident that many clients will gaze into your eyes in an attempt to determine the truth, with an interest in removing the old one as soon as the problem is resolved.

The 26th of January, 2009 Hello, Nathan.

That portion of material should have been included in an other article entirely.

It’s encouraging to see you asking questions, though.

Moreover, the new starting capture has a much improved signal quality.

Thank you for your interest, gentlemen.

You also observed that there was “a significantly healthier peak voltage.” Did you take a different measurement for that?

The 18th of January, 2009 Thank you very much, guys, for your nice words.

Or are you attempting to tie me down on a certain test that you would have conducted and therefore assuming that I should do the same thing as you did?

Please accept my heartfelt greetings.

Continue to send them in!

Car Hard Start – in Cold Weather only

Greetings: I now possess a 2003 Ford Explorer Limited V6 4 Flex Fuel with around 142K miles on the odometer. Approximately 6 months ago, I began to notice that my truck was difficult to start. (As difficult as it is, it will not turn over. All of the lights turn on, the beeping starts, and the engine revs and revs but doesn’t catch). Once it does start, it has the potential to stall out, or attempt to stall out (the stalling out is not consistent). If the temperature outdoors is above 50 degrees, the machine starts up without a hitch.

Once the temperature outdoors reaches 32 degrees, you can continue for up to 10 minutes.

Once it has caught up, it will begin to rev on its own.

As far as I can tell, only when the engine is completely cold, as I would describe.

Battery, spark plugs, and wires have all been replaced.

The problem has been identified by two independent technicians, both of whom have essentially written off the vehicle (as in they said, It start fine this morning, had to hold the key longer, but it started, 1850 please, have a nice day).

All agree that there are no vacuum leaks, that power is being supplied to the pump, and that everything checks out well.

Others have said that they want to replace the starter, but have failed to explain to me why I do not have starting problems at other times.

Good results were obtained.

The temperature is 91 degrees.

14.18 volts under load 14.02VNo.

13.8 Amps of current The battery is charged to 39.0A.

According to one mechanic, my starter is on its last legs and that I should start there.

Any ideas on what it may be and why it should be considered?

There is a coolant leak somewhere in my system, and I’m not sure where.

They all replied no, and that you were the starter.

Near the point where the rubber home is attached, there is a white residue on top of it.

However, there is no evidence of white residue anyplace else on the vehicle. There are no rips, tears, or cracks in the home that I can see. So I’m not sure if it’s just a leaky component, as this part has already been repaired once, approximately two years ago. Thanks
