Electronics won’t let me start my Z and OBD port and ECU won’t connect. Need a mechan

osburnrs · 03-27-2020, 05:32 AM

Well I have to say that 2013-Z33 was spot on here. Months and months of tears and hard work and about $7500 later, my baby is running again. Another 6 weeks at the dealer, 2 or 3 more ECM’s and 6 coil packs seems to have fixed her. I changed the wiring harness before it went to the dealer so I’m thinking it shorted and burned 5 out of six coils. These then feed high voltage back to the ECM’s and fried them. I had even installed new plugs while it was down and never noticed the burnt coils. Of course working around the Stillen SC doesn’t make it easy. It took Nissan 2 master techs and an engineer to find what Z-33 had already hit on. Had I stayed on that path, I probably wouldn’t have missed 9 months of driving and heartache. Salute to you Z-33 on the great call!!!

Thanks for the update!

Since you have the ECM open, could you post a picture of both sides of the ECM circuit board?
