i have a 99 malibu and the theft light has been on the dash for a long time.But every now and then it will not start untill you wait 10 mins,then it does.I was reading how to bypass the passlock thing on these cars and before i could the car will not start at all now.I thought it was the fuel pump but when you turn the key on it prims and everything.I can sit there and crack the car over forever but now it wont start.So i disconected the battery and did the 11 mins on then turn key off and 11 mins on.Then tried to start it and now it just clicks but does not turn over just woundering if anyone knows what i should do at this point.The car is a winter beater so i dont wana put alot of money into it just would like it to start thank you for your help.

The security system will let it start and run a few seconds and then shut it down.
Does it sart a few seconds and than die?

The relearn procedure is key on for 10 minutes untill light go out and the key off and than on for another 10 minutes untill light out and repeat key off and then on for another 10 minutes untill light of then off and then see if it will start.

There is a big post someplace on here on bypassing the system.

But first make sure it is the security system shutting it down after a start and die in a few seconds.

Drop down 12 or more post.
