And the critical ground wire Bill and 4DRUSH mentioned.

Just read your post. Ever fix problem? I had a no spark once & got stuck on the road. No code, Turned out the wire harness chaffed against metal bar that wrap harness around top of engine under injectors & wraps a 90 deg turn behind intake manifold in front of firewall. Its a tight fitting harness. I took out the metal bar & used zipties after repairing chaffed open wire that was grounding against that bar. That was a cheap fix & AAA paid for the tow home.

I'll take a look , it's hasn't been a top priority.....other things seem to be popping up and keeping me from looking at my wife's vette. I did find
a loose wire that goes to the rear defroster . When I find the bug ...I will post it.

I had this problem with my 97. crankshaft frayed and when I went to start my car it shorted out the pcm.

I hate it when a good story has no ending.
