Question about 1999 Pontiac Grand Am GT
The vehicle will stall out after about 30 minutes. The old computer was replaced with a used one. It still does the same thing.
ABS light will come on and off. The gas gauge will give different reading after it stalls and the car is restarted.
Sometimes it will start back up with no problem other times you have to keep cranking on it to get it to start.
There are 2 possibilities off the bat i could think of. first suspect would be fuel pump. they can be very intermittent with gradual progression. next common problem for this symptom would be security issues. make sure youre using genuine GM key. ck body control module for codes. code b2960 in HISTORY would indicate faulty bcm. there are also issues with invalid "passlock" data whcih is a security sensor attached to ignition switch. tricky to replace and reprogram so be careful.
