I have a 1989 (or 1991, I can't remember) Buick Park Ave. that is not starting. It has a new (yes, charged) battery and newish starter. When I turn the car on, the interior lights, cd player, headlights, heat, air, wipers, etc. all work. But when I try to start it, nothing happens. It kind of "hums" but doesn't turnover or even struggle to turn over. Just silence. And the car does start sometimes. Completely at random, although usually when it's warmer outside. I've been told it's probably a loose connection to the solenoid. Or possibly needs a new ignition switch. Any other ideas? Anyone else ever have this problem?
Thanks in advance!
