Is there any pattern to when it stalls? Is it a complete stall while in motion? On the freeway? At stop lights? -- This could be so many things more information would help narrow it down.

we had a customer come in 3 months ago that spent over 1100.00 on replacing all sensors, and coil packs. his did the exact same thing it would die at any giving time.

he brought the car to use and we hooked up a fuel gauge and drove the car for 4 days before it finnaly died on us but it was the fuel pump shutting off. we replaced the fuel pump and problem was solved.

Suggested Repair

Check fuel pressure and the fuel pump. A similar intermittent stall was traced to the fuel pump shutting off; replacing the fuel pump resolved it after sensors and coil packs had already been replaced.

Conversation Summary

The owner of a 1992 Pontiac Grand Am V6 reported intermittent stalling a few times a week, with the engine restarting afterward. It happened with no clear pattern, hot or cold, while moving forward or backing up, and often when coming to a stop; shifting to neutral allowed it to restart. The owner suspected the crankshaft position sensor. One expert asked for more details about when it stalled. Another expert described a similar case in which sensors and coil packs were replaced without success; fuel-pressure testing showed the fuel pump was shutting off, and replacing the fuel pump fixed the problem.
