2001 Pontiac Grand Am GT 3.4l V6. Security light on. After it starts for about 2 seconds and dies.
The car will start and die after about 2 seconds. Has a anti theft code in computer.The security light will stay on after the car dies. Have tried to relearn it as a temp fix but the light will not go out. Have waited as long as 20 mins. The door locks are not working either or trunk lock on drivers door. The key fob is not working either (battery may be dead in it).
We checked fuses. Key cylinder will allow the key and turn over with no problem. Just went to get back in car and would not fire up again. It also has a code U100 code communication. I think that was what it said i did have the radio unplugged at the time. Was back in when i tried to relearn the system. The radio doesn't work either. Gives me the LOC warning on the radio. Whats the process of elimination. Thanks a lot!
Answer: Well, the radio could be a blown fuse, or a bad radio. I assume you checked all the fuses.
Pontiac Engine size = v6
Security warning light is flashing.
Question: My son was being bad with our car! Hit a light pole, we have instructed him that he is to do all the repairs himself and such..
He as removed the bumper .. (first part of the repair). Also the car was drivable before he removed the front bumper. Now the car will not start with the security light blinking. We would like to load the car onto a dolly to take it to his uncle's house for the rest of the job.
Answer: The security light flashing would have nothing to do with the front bumper being removed. If it was in such an accident, there is no telling if any wires were damaged. You might start with a theft / security relearn procedure. The fact that it is flashing means the car is not seeing the correct security code from the key ignition. Without the year and model of this Pontiac, i could not even tell you which relearn procedure to use.
