Tough question, the past few times I tried it hadn't started. So for good measure I cleaned the ground on the bulk head but it looked fine anyways. It was turning over before I did that but wouldn't catch, I then found out it was in 3rd gear when I was trying to start. Tried today when it was in first and it came close (chugged forward a little b/c the clutch wasn't fully depressed) but then the battery died (tried too many times I guess) so I'm recharging it now. I doubt changing it from 3rd to 1st did anything but this car seems to be possessed at times.
My concern is I figured the ground was there for a reason and trying again with it disconnected could be dangerous.
