I've had similar experence with a Bonneville SSE, it was exhibiting all kinds of crazy symptoms, like the anti-theft system not allowing the car to be started, etc. Codes pointed us to fuel pumps, door sensors, etc. Which we changed to no avail, even bypassed the anti-theft system, no good. Finally found it turned out to be an simple intermittent electrical connection on the AC compressor. Unplugged and cleaned it, reconnected tightly, and viola, it starts and runs perfectly! These Pontiacs are bizarre creatures...
A seized AC compressor will tear up the belt... if it's a serpentine belt, or a belt which runs any other components necessary to the car's operation, that'll eventually cause it to shut down.
If the clutch on the AC compressor has seized, the engine can in some situations stop running. The compressor could be bad but it is also possible that the clutch only is bad.
A bad timing belt could make the engine shut down but it would only happen once, not sometimes.
Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.
A bad compressor belt can cause a whistling noise while running the air conditioner. A bad engine can also cause this noise.
A bad fuel injector can cause an engine to continue running, for a few seconds, after the engine to shut off. The engine continues to run because of excessive fuel in a piston.
you have a bad crank senser
The compressor could be bad.
compressor contactor is bad. probably stuck in the closed position.
"A BAD TEMP SENSOR" Or it could probably be a broken relay of the compressor. Try looking at that one as well.
the ac compressor is bad
If the compressor is not engauged, it is ok.If the compressor is not engauged, it is ok.
