Recently purchased a 04 350z Touring.. I have consult 3 software ran codes only came up with a u1000. No other codes trouble shot the system and discovered the IPDM is bad. Replace IPDM. Now Im reading codes. My problem is I have no spark. I am troubleshooting the harness ecm with a field service manual pin by pin wire by wire. I am leaning torwards a bad ECM. Running all factory OEM coils have power and grounds to all coils ohmed all the trigger wires back to the ECM there all fine. Checked ground harness and power to the ECM there all ok or battery voltage. MY main question is when I fire up my consult 3 it tells me the ignition key is off... when its actually on. I trying to figure out bad ecm or is there a circuit I have missed that triggers the ECM to know the key is actually on when the key is actually on. I have been troubleshooting this vehicle for about 2 months. I know I have to replace the engine because I have no oil pressure even with a manual gauge.. But do not want to install a replacement engine until I get spark. Cam and Crank sensors are reading on the Consult software.
Codes currently on ECM are
po113 not worried about this one
p1065 worried about this one
p1121 not worried relearn pedal
p1122 not worried relearn throttle
C1131 ENGINE SIGNAL 2 from the ABS
also IGN Timing is 110 BTDC have no idea what it was before I re timed it to all the marks intake exhaust both sides and the crank all like up where they should be It was one tooth off when I opened it up. Dont know if this is right could the crank be 180 degrees off? I have no idea what where or who the previous owner did to this vehicle. all the timing marks line up when Im suppose to be TDC.
This is just a project car for me and my 14 year old son. Ill keep hammering away at the FSM till I find it. Hoping for some Consult GURUS.
If need be I can post a video and include a link if necessary.
