Hi, I have a 91 318i with a m20b25 swap, the car was running well and suddently stopped to start, engine cranks and make fire . I lost my 12v to the fuel pump. I jumped it and the car still no start. Could it be the crank sensor? Does it give the signal to the injectors and fuel pump ?

Crank sensor will not remove power to the fuel pump.
I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose. - Nick |
