Crazy behavior and no start - 5/12/2008 9:56:49 PM    deflator   Posts: 2 Joined: 5/12/2008 Status: offline I'm trying to help my friend fix her 01 neon thats been sitting for 2 years. I believe her mother jumped the car backwards, positive cable on negative and vice-versa. When I try to jump the car, it honks and the lights turn on and off in time with the honking. I disabled the alarm. When I try to start it, there's no start and the locks go open and closed rapidly and the guages dance around. Very strange. So is the PCM fried? The fusebox looked fine, and I didn't find any burnt wiring anywhere. Post #: 1

The battery is toast, I swapped in a good one and the locks and guages stopped going nuts. The PCM is giving the right DTCs to the codereader...so it might be okay. The starter however, is just making a humming noise and not starting. (in reply to mjj1587) Post #: 6
