Hey guys, this is very common on VQs after a swap. I've done this before.. and a bunch of friends. The reluctor wheel for the crank sensor is on the flywheel. The flywheel has a hole on it that needs to be lined up with a pin on the back for the crank, if it is not lined up it will have a bad misfire (if its only off one bolt) or it will not fire at all if its completely off. Just rip the trans out and check it, esp if the customer did it him self.

There’s usually a difference in the Cam/Crank reluctors between USDM and JDM, would definitely cause a crank no start!

Also, a common issue on these engines is the cam positioning sensor will go bad randomly without warning. There are two on each side on the back side of the motor. The engine will crank and not start when just one goes.

Its the NATS that has failed on the vehcile. It's an extremely common issue with the G35s. I had it happen with my old 2006 G35 Coupe. I had to send off the ecu to get reflashed and the deleted the NATS system from the ECU. Solved it right away.

I had a bought a 03 350z had a bad gasket so I ended up just a doing a jdm motor swap on it and I’m literally in the same position rn trying to figure out why it wasn’t turning I had changed the ecu, got a new wire harness, tested the starter , thought it was a grounding issue so I put a lot of ground wires and after everything nothing worked until I noticed the engine wasn’t spinning and it was locked up that’s why you always get warranty guys
@kalebjanson73056 ай бұрын
Did one of these a while ago, was an HR motor though. The fans coming on immediately is a Nissan failsafe, it means there's a problem with the ECM reading output from the motors sensors which typically means the pins are switched in the engine harness plug. Another issues was the pinouts for the cam sensors. The cam sensors on JDM motor are pinned opposite of the US motor and read backwards when looking at the waveform for the cam pickups. The crank sensors read differently as well and required me to use the US crank sensor but swap the pin positions for it in the JDM plug so the it would read correctly. Swapping the harness was a good thought. But you still have the sensors themselves outputting the signals wrong. I love wiring & electrical so this would be my playground. This on top of the Nissan IPDM and CANBUS systems are a RATS NEST of circuits lol. Makes it fun for people like me to go make it work.

Easy tip for Nissans if cooling fans come on the second you turn the ignition on it’s in fail safe bc the ECM isn’t communicating which means bad ECM or bad connection somewhere in the harness

With ANY belt drive engine - not applicable in this case - first thing I do is check the belt is still driving the cam-belts - with older engines it was a simple case of popping the dissy cap and seeing it it turned, or removing the oil cap and seeing if the cam/cams was/were turning.
