Why does my car stall when I Turn Off the engine?

If your car’s engine stalls while running or at idle, it is a clear sign you are having some problems with your fuel pressure. This may be due to fluctuations and sudden drops of the fuel pressure. Today’s electronic cars have a fuel pressure sensor that intelligently calculates if anything is going wrong with the fuel pressure.

What to do if your car won’t start after running out of gas?

Which is worse for a diesel injector, gasoline or alcohol?

High combustion temperatures alone will shorten fuel injector life, gasoline makes the problem worse.

Alcohols work as a water dispersant in small amounts, but also attract water in large amounts.

What should I do if my Duramax engine wont start?

But even if it is the first time you stalled, it could still be due to a bad fuel pressure sensor. With a bad fuel pressure sensor, the engine will not receive the proper amount of fuel for its internal combustion process. Because of this, the engine won’t release the right amount of energy for the rest of the car’s components to function properly.
