Hey guys, long time lurker, first time poster, appreciate all the help I have gotten from this forum without ever having to post a unique problem!!
This time I couldn't find a thread to help though. The problem is that my ECU was on the way out. I had the telltale fuel guage error sporadically appearing and preventing the car from turning over. I never bothered bypassing the starter relay and bridging the starter motor, I just decided to try and find a second hand ECU rather than spending the $1000 holden wants to replace with a new bosch model.
So I pulled an ECU from an identical car. 175kw auto sedan. I fitted it and tried to start the car. It shows no fuel guage error but didn't turn over or start to begin with.
I reset it with neg off the battery and it turns over but doesn't fire.
I was told by my mechanic friend that if the cars are the same the ECU should just work without any programming etc... I'm now wondering whether that is accurate or not. Are any of you familiar with replacing the ECU with a second hand unit?
