My 1993 Buick Le Sabre won't start. All the dash lights come on, I put a new starter, etc. and it still won't turn. I don't even get a click when I turn the key. Open to ideas......

Welcome to AF. Got 12 to the starter solenoid wire in the crank position, good battery and engine grounds? Possible trans position switch also. no quick answer here, basic circuit tracing is in order.

How long does the security light stay on after the key is turned to the run position?
