Default 2002 Pontiac Grand Prix Stalling

Car stalls upon start up -every time, then often, especially when warm, it will not hold an idle.Sometime if we are lucky the idle will click in and hold okay.It has done this for months.Sometimes we can drive it just fine for hundreds of miles..It does not like starting and stopping and restarting on local city errands and often looses holding its idle.

Our key also gets stuck and we have to use a 10 penny nail up the back of the column hole to clear it our again.

Now the car is worse and is lurching and shifting funny it seems like, or the fuel pump is dying intermittently.It does all of this worse when warm then stopped and restarted.Its fine in the cool mornings - and even in the afternoons on the way home but after that driving it stop and go again is an impossible annoying chore.

Sounds like a couple different problems. This could be one of them:

Or its a relay for the fuel pump. As for the key getting stuck the shifter interlock cable might need adjusted.

sounds more like the ign control module. i would try starting it cold and heat the icm up with a heat gun see if it cuts out. another common one is the crank pos sensor, those are hard to test though.


i would start with some wd40 and work the key in and out a couple times, sometimes they just get where they hang up
