Hello NICOCLUB Members : New here so bear with me !!
2003 Nissan 350Z touring edition engine electrical issues after new engine install ...
completed tests all static grounds checked ohmed and continuity tested for engine sensor grounds and body to engine grounds come back good , IPDM ECM relay good but replaced with OEM New Relay .
We are getting a no fire @ cylinder # 3 and no pulse to injectors either , havnt noid tested injector harness yet but have ohmed and continuity tested the sub harness for injector #1 & #3 & VVT sensor plug comes back good ?
All cam and crank sensors good . We are leaning towards a bad ECU but are having no luck for a Pin out diagram for this 2003 car and having no luck locating in the service manual down load ?
All Timing set to spec and double checked as well , even went the smell test on the ECU with No Burnt Smell .....
Any help and advise for this conundrum of a issue we"re having would be greatly appreciated .
Im leaning towards ECU issue with this car but customer is requesting additional tests of ECU before being sent out to Module Express for repair ....
This is a OEM ECU with roughly 80,000 miles .
The car was towed in to shop for a engine misfire issue on # 3 , after scoping cylinder and compression testing engine extensive damage was done to cylinder # 3 hence replacement engine being put in . I want all the gremlins fixed before the car leaves our shop and have a happy customer with everything working .
Please advise and thank you for your help
