1989 Bonneville - Starts, Doesn't Start, Starts, Doesn't Start

[joshshrag]

I have a 1989 Bonneville.

Most of the time, she starts just fine. However - if I have her out, then park her and turn her off - 1 time out of 5 if I try to start her up within 5-30 minutes, she will NOT start. If this is the case, I know that if I leave her sit for 1 1/2 hours or so, she will start just fine.

If she's been sitting overnight or even for a few days/weeks - she ALWAYS 100% starts fine.

Again, she only fails to start if she had recently been running.

Any ideas what is going on here? How to address/fix this problem?


Thank you!
