My car keeps dying and no one can figure out why. It only dies when it is really cold outside and after running for a while. What happens is that when slowing down the heater slowly cuts out and then when stinkin car dies. The car restarts without a problem. No engine light comes on so nothing comes up on diagnostics.This has been an ongoing issue but only when it gets cold. Of course it doesn't die for the mechanic probably why he can't figure it out. Any suggestions or anyone with a similar problem?

I had a problem kind of like that..I had drilled into my fuel line while putting on neon lights, the car was idleing ok but as soon as you tried to drive it it died....you may have a problem with your fuel pump, you may also have a problem with the idle controll...or maybe your air fuel mixture needs to be changed....when the car dies does the power stay on?

I vaguely recall having a Grand Am with a similar problem a while back. If memory serves, (and it may not) the Oil Pressure Sending Unit was sending false low-pressure readings to the PCM and engaging the Fuel Pump cutoff. This would explain why it only happens when it is warm and why it restarts every time just fine - a vacuum leak won't do that.
On a diagnostic scanner the mechanic would have to watch the readings from this sensor up to and during a failue to confirm the diagnosis. Otherwise you could just replace the sending unit (not that expensive really) and hope for the best.

Piece of cake. Have your mechanic check for vacuum leaks. You have one. Vacuum leaks like the one you are describing may not be close enough to the mass air flow sensor for the car's computer to detect it. If I had to guess, I would guess you are running a four banger and the bottom center intake manifold bolts are loose. If that aint it listen to NPR and ask click and clack the tappet brothers on their call in car trouble show.
See ya down the road.

Sounds like and ignition switch, the contacts commonly get burnt spots on them and sometimes will not send the correct voltage to ignition fuses. Have replaced a few.

i thought by 02 gm put the crank sensor code in but maybe not.
it used to be that the earlier gm's did not have a crank sensor code so you would not see it.
other that that I will reiterate once again G.M. fuel injectors are junk

i own a repair shop,and i have seen a few do this before,and the only thing i can tell you is i have replaced some fuel pump relays ,before and that has repaired a few of them, but i wouldn't do that unless i was sure that s what it was,yours is one of those things that it almost has to go out before you can find out what it is,at least if it would just stop running all together ,you might could find it,good luck with it,i hope this help,s.

If Your heater turns off,radio resets,ipc goes crazy, it would seem that you are losing ignition power. The ignition switch would be the most likely culprit...........
