How do you reset the theft system o a 2000 Pontiac sunfire gt what causes it?

Answer 1

I have the same car with the same ussual sunfire electrical problems From all the hours of trial and error and extensive research that I have done, my conclusion is this.

GM is very aware of this problem but does not care, these problems are continuious for the life of the car.

GET RID OF IT!!!!!!FAST it will end up costing you thousands to keep fixing a sunfire.

Just wait till you get the dreaded headlight wiring harness problem.

All I did was change my battery and it went into antitheft mode. What a joke that you must have a dealership involved just to change your battery, tell me that wasnt part of their master plan.

If you have solved this problem please let me know, Ive done everything Ive learned to reset it but it still wont turn over.

While driving sometimes the theft system light would flash on and stay on and my car will act funny while its on. it will feel like i am hitting the breaks 2-3 times in a row and quit. Then usually the next day i will get into my car and try to start it and the light starts flashing on and off. It will crank over and start for about 2 seconds then just die... The research I've found is that the starter may be going out or the egnition switch may be bad..but after messing with my car for about 15 minutes on and off, I tried this. Lock and unlock doors then put the key in the ignition and turn key forward to the on position without trying to start it, put the gear in Neutral then back to Park. For me that worked, the light stopped flashing after a few seconds and then started.
