At first it was just the anti-lock lights were coming on once in a while and this would cause the turn signals to stop working, etc. Now I'm lucky to get it started, I'll put a key in (I have three of them, they all do it)...and I could turn it two or three times and it might start, I could turn it forty times and it might start...its completely random. It would seem a new key ignition would be an obvious answer, but since that's not where the problem started I'm not sure that's where the problem is. Has anyone else experienced this on GMs from that time frame? Any do-yourself-suggestions? Thanks.
