My 99 pontiac grand am will start and run when cold but will not stay idling when hot and stalls?
I had the same symptoms with my 97 GTP 150,000 miles - it would start and than stall immediately in hot weather. It would sometimes start and run OK in cooler weather and than stop after driving when it got hot. Sometimes the car would run OK again after being allowed to cool off for 30 minutes. The problem got worse until I could not drive the car.
After much parts changing and $$$ spent I discovered that the fuel pump electrical circuit has an .8 ohm power resistor that was going open intermittently at high temperature. I replaced the resistor with GM PN 88951182 ($40) and it fixed the problem.
You can diagnose this problem yourself when the car won't run by disconnecting the resistor (it is in the right front wheel well) and jumping the mating connector with a paper clip. If the car runs with the jumper installed you will know that the resistor is the problem. However, the resistor and connector is hard to access so you may want to just
go ahead and have it replaced now rather than wait for it to fail again so that a positive diagnosis can be confirmed.
Good luck - !

If a 1998 Pontiac Transport 3400 starts but stalls out what should you check?
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
