Your Ford Mustang often stalls when the engine is cold, but only in that situation, and not at all when the engine is hot, and you have problems finding its origin? This problem, although less dangerous than an engine that stalls while driving, nonetheless ought to get your attention because it could be the start of a more serious problem in the future.
In this article, we will tell you about the different problems you might face when your car stagger in cold start so that you can react more efficently and not necessarily go to the mechanic, which often charges a high price for the service and does not always solve the problem.

Different reasons to stall for a cold engine.

First, we will focus on failures associated with mechanical problems. The second part will be devoted to electronic problems.Stalls-when-cold-ford-mustang

1: Mechanical failures on your Ford Mustang

First thing to think about, the idle actuator. As a reminder, the latter’s role is to regulate the engine speed. It may be difficult for the latter to connect to the engine while the engine is still cold.
Another simpler factor, but also common in these cases, is that the battery is probably low, and therefore does not have many reserves until the engine has started. This denotes that after “heating” the engine, the battery has stored enough energy to keep your Ford Mustang on. However, it has difficulty maintaining autonomy once the engine is switched off. Which would make clear why it only chockes cold.
Also remember to check your dashboard, and if, by any chance, an indicator light is not lit.
Then again, if your car always starts the first time, it is very certain that it does not come from your battery.
If the battery is not involved, look at some of the parts to be cleaned, such as filters, injection pump, or pressure regulator.
Remember that a simple, heavily dirty part can disrupt the entire mechanism of your Ford Mustang. Check all your parts to be able to exclude this type of failure.
Once mechanical breakdowns and fouling have been put aside, let’s look for electronic parts that could cause you problems.

2: Electronic failures of your Ford Mustang

The first essential parts are the onboard computer. the MCU (Motor Control Unit) acts as a system for exchanging and sending information throughout your vehicle. Electrical signals are received, analysed and sent back as information to the several parts of your Ford Mustang.
For example, when you turn on your indicator, your MCU box receives the information, processes it, and then redirects it to your flashing room, which will then light up. We have taken here the example of the indicator, which would not stop you from driving. If this information was associated to the engine of your Ford Mustang, then in this case it may stall cold.
Furthermore, let us talk about the calculator. This important part of your vehicle is a central component of a system called an embedded system. This means that it electronically deals with the various functions of your vehicle, and therefore the ignition of the engine.

Directly linked to your computer, the TDC sensor.

In fact ,the internal combustion motor must have an accurate ignition timing setting in order for all the cylinders to start in the correct order and at a specific moment. If the TDC sensor is broken, it will not transmit this information to the onboard computer. Consequently, as a safety measure, the ECU will stop the ignition system and your Ford Mustang won’t start.

At last, you might want to verify your alternator.
It is necessary for the engine to start because it turns the battery on, and the engine producesthe electricity required to keep the battery charged when you drive.
This means that indirectly you could have a battery problem. If your alternator does not provide enough electricity to your battery, it will, therefore, be incapable to keep your Ford Mustang on.

3: Conclusion

As we have seen in these various motives of cold stalling cars, this often leads back to the battery or directly related parts. However, this may not be the only cause, do all the necessary tests to analyze the right functioning of each part. At last, the last thing to think about with Ford Mustang is to ask yourself this question: have you lately started refuelling at a new gas station? If so, it may be inadvertently degraded due to contact with water or impurities. This would affect your engine, which could start to stall quickly.
However, if this does not happen as soon as your engine is hot, then the impurity of the fuel is exonarated. The problem would be repeated no matter if your engine is hot or cold.
