Yesterday the car stalled at 35 miles per hour, and I couldn't start it again, it would crank, but not turn over. I waited 35 minutes, and it started fine. Same thing this morning, no problem....Fuses all check ok. Anyone have ideas? Or where can I find a pin out diagram for the main wiring harness connector? Any help appreciated. Also, not sure if it's related, but the car will run "rough" at certain times...like it's missing a cylinder or something. It could be while at a red light, or just after starting or after running after 40 minutes.....I am not sure if all these things are related or not, and I know electrical problems are difficult/ie expensive to find, so trying to do some legwork myself.
"No start" conditions can be tough to find. Any CE light? It's helpful to konw if it's fuel related or spark related.

I would check for bad grounds. If it's a wire bolted to a body member I would take it off and clean it. Do a search on this forum. I've done a few post about this.

I would goto your liberary and see if they have a good book on your car. The Liberary near me also has AllData on it's computers. Very helpful. I've also gone to the dealer and looked at their books.


Regards

Dan
