I'm having this same problem with my 2003 Accord 4cyl. What ever happened? I suspect something was found and fixed, but I could use to see what niknik57 wound up doing.

 

Sometimes members don't post their results. If you are having the same problem, the testing is similar. Check for 12V to the smaller wire when the car is not starting. Then start a new thread, so it doesn't get confusing on this thread.

Good luck.
