Asked by KATHY Jun 12, 2021 at 11:55 AM about the 1997 Pontiac Grand Am 2 Dr GT Coupe

Question type: General

We have put in a fuel pump, all sensors are good, new fuel pressure regulator,
changed throttle body, checked fuses and I don't know what else. It wouldn't
start with out priming, then when it did start it wouldn't keep running. Please
someone help me out here.

Crankshaft position sensor would be my first suspect. If it's not working the computer will not know the engine is running and will shut down the fuel pump after a few seconds. Hope that helps! Jim
