  • 1998 PONTIAC GRAND AM
I have a 1998 Pontiac Grand Am, 3.1 litre which has approx. 135,000 miles and is automatic. Just had a diagnostics test done and my o2 sensor #2 was bad which I just replaced and about 2 years ago the fuel injectors were also replaced. Now my check engine light is on and the car will start up right away sometimes or it will take 2-5 times to start if not more. Also when I park the car and leave it running it just shuts off. I would bring the car in to get it checked but I have had the problem to where even though the check light is on they can not diagnose the problem and I am not wasting no more $. If someone could please give some advice on this? I would be so relieved. Thanx

Hi
i would check the fuel pressure, first with the key on start and then check for leakdown, the pressure should be at 41-47 psi, you should be able to pick up a guage at any local parts store that will fit a gm, the test port is on the fuel rail under the hood, check that and let us know
