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.

As someone who’s had to fix so many things on my stock 03 G35 it’s good to see the pro’s get stumped on this stupid thing too. Loved the video and share the same pains 😂

My friend did a jdm swap on his 04 g35 n it was the flywheel having an extra tooth making it lose the position of the crank and losing spark

I’ve done about 6 vq swaps and I never ran into this issue … they missed something probably the flywheel is off timing

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.

Hey, if you guys need someone to edit the back ground noise out of your videos I’ll do it in like 15 minutes for you free of charge.

the service for this job was worth more than the car.

Fans kicked on as soon as you turned the key. That means the ecm is done for. Try pulling codes and see if the ecm communicates back.

spark - yes, gas - yes, but wont start.... ECM or Timing belt. if the motor has been swapped before.. ECM.

I like the way you guys come together and think of solutions. Each person is looking and giving insight on how to get the job done. No one is sitting around being a dick . Great work guys, earned a subscriber

I love your guys videos. It's awesome seeing the day to day work as mechanics with all the weird customer complaints, the funny moments and the frustrating parts of the business. Awesome content 👌 10/10

Love the videos! I appreciate what you guys do

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

Hey ya Will & the team .

Love the videos yall. Keep it up!

I would love to work with these guys! Funny, genuine and they knkw their stuff

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.

This car is notorious for the cam sensors, If they are bad it wont start sometimes clearing the code will fix but not always.

Thanks for the tips, plan to do a JDM k24 stock swap for longevity... Will reuse most USDm parts and wiring for my new motor

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.
