Im not sure if im doing this right. Anyway, I bought my son a 1992 Cadillac DeVille from a police auction. The car wouldn't start. So I put a new battery in. It still won't. Replaced the ignition switch. I've made sure the ohms for ignition are correct as well. It's not the starter either. When u turn the key, all the lights come on and everything works. But the car won't turn over. Not even a click or a chug. Nothing. Can someone direct me to what it might be? I've had the car at the mechanic since we got it 2 months ago and im sure I've done more work on figuring it out than he has. Thank you! :-)
