grand am will not start till security light goes off?

Question

motor will turn over and over but will not start until light goes off(security light). sometimes it takes fifteen minitues to start

Answer 1

your security is disabling the fuel system. go to the car and turn it to the on position, don't start, leave key on for 10 minutes. the security light should go out and the car will start. this is the relearn procedure for these cars. if the security light continues to do this after the relearn you more than likely will need a new lock cylinder with the pass lock sensors. take it to a dealership as all will have to be reprogrammed. good luck

Answer 2

barb_wyre 2003 is right on the money! The 2 things I see most often with this problem are the ignition lock cylinder/passlock sensor assembly and water intrusion into the Body Computer Module. The water intrusion problem is more rare than the passlock sensor issue.
Hope this helps.

Answer 3

The internal anti-theft system is detecting a problem at times and disabling the fuel injection system. You will need to get the codes retrieved from the module. Usually the codes say something like invalid voltage or something like that. After all is said and done, it is normally a faulty ignition switch assembly that causes this. Get it checked first though. Good luck.
