Why does my car engine not want to start?
If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.
What happens if the crankshaft sensor is missing?
If it missing it will not activate the fuel pump relay – preventing it from pumping fuel in case of an accident where a fuel line gets ruptured – but I’ve already replaced the Crankshaft sensor, and tested it with Vag-Com to no avail.

What causes the engine to stall when the ignition switch is on?
If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls.
Why is the Check Engine light not coming on?

Why does my car not start after putting gas in the tank?
What you are doing wrong is running the tank lower than 1/4 the fuel pump uses the fuel as a coolant, so if you run it below 1/4 the fuel pump is out of the fuel so it starts to overheat. Now when you do replace the fuel pump make sure you replace the strainer and the fuel filter.
What happens when you run out of gas?
If you ran it out of gas then the fuel pump is most likely fried, they don’t last long once they start sucking air instead of fuel. That’s why you never run a vehicle with less than 1/4 tank of fuel, it keeps the pump cool and they won’t suck air at 1/4 tank. 2 people found this helpful.
What to look for when your engine won’t start?

Why does my Mustang crank but won’t start?
If timing is too far advanced or retarded, this can cause hiccups upon startup. Ignition timing needs to be up to par as well. If the ignition timing is too far off then this can cause your starting problems as well. Everything we have covered so far has to have the spark to complete it all. Without spark, you will never have a running engine.
