Howdy......this is a continuation of the below topic/thread, but since it is now going in a different direction, I thought I'd start another one.
So I thought it would be straight-forward: replace the coil and plug and go. Not quite. We put another coil and plug in, started the motor, and it was still missing. We ran it only for a minute to make sure. Pulled out the coil and it was hot. We pulled out other coils that were just lukewarm.
The mechanic called a Honda dealer friend and explained the issue. The Honda mechanic said the same thing had happened to him one time. The Honda rep told him to replace the ecm and the problem went away. This is almost a third-person account, and I don't know that it's definitive, so before I replace it I'd like to gather as much feedback as possible.
-Has anyone experienced this?
-Can the ecm be troubleshot and/or repaired?
-are there any tests that can be done with a meter to verify?
-is there anything upstream from the ecm that caused this and can do it again?
-there are 2 ecms listed: one is a "sup" (023) and the other is a "pri" (043). Do I need both or just one?
Help!! Thanks......
