2000 grand prix stalls

Welcome to AF

It would help to include the trim level and engine in your post.

Also, try to be a little more specific. Does it start then stall?, while driving?, coming to a stop?, randomly?,etc...

I merged your two threads. In the future, keep all posts in the same thread for the same issue. Just click on the thread name, then scroll to the bottom to add your new info. thanks

On your issue, can you please be more specific as to how the car stalls (at start up, randomly while driving, when coming to a stop, etc...). Also, when it stalls, does the tachometer drop to zero and the trac-off light come on just prior to stalling?

[jay44]

trac light does not come on

[jay44]

changed pump filter and relay

Do you have a service engine light that remains on when the car is running? If so, have you had the codes pulled?

[jay44]

engine light does not come on. Its just dies and the only lights that come on are the oil light and battery light

need help

I would suspect a crank position sensor, but since you say you get no tachometer drop to zero or trac-off lights (which almost always accompany a bad crank position sensor signal) I couldn't say . I'm sorry, but your symptom explanations couldn't be more vague, which makes it virtually impossible to narrow it down.

while driving it dies, no service light or trac light. wait a few seconds it will start back up and drive. eventually it dies again.

had a fuel pressure test done, when car is started,pressure dropped to 40 psi. thats when i changed the pump and filter. car still dies

When you first turn the key on before starting the car, does the service engine soon and other warning lights come on then go off. They should, as the car will do a bulb test at key on). If not, your Service Engine light bulb may be burned out or missing.

does it die even when driving at a steady speed, or only when accelerating/decelerating?

[jay44]

service engine light does come on at start, so it appears to work. the car will die while driving at any speed, and at idle. the tach is fluctuating at idle between 600 and 1000 rpm
