Re: I have a 1997 buick centruy when it gets dark the automatic head lights come on my car shuts down and if i put in reverse the car shuts down but it starts back up do any body no what this could be

It sounds like there may be an issue with the headlight switch or the reverse light switch on your 1997 Buick Century. When the headlight switch is turned on, it sends a signal to the engine computer to shut off the engine. Similarly, when the reverse light switch is activated, it also sends a signal to the engine computer to shut off the engine.
It could also be possible that there's an issue with the electrical wiring of the headlight switch or reverse light switch, which is causing a short circuit and shutting off the engine.
I would recommend checking the wiring and connections of the headlight switch and reverse light switch, and if everything appears to be in order, then it's best to get it checked by a professional mechanic. He will be able to diagnose and repair the issue.
