cranks but no start no spark
 

hello my g35 2005 it cranks but dons't start and also it dons't spark or injector pulse i check everything i dont know what to do

Is your security light solid red when cranking? If so it's NATS interlock and your transponder in the key probably ghosted on you. Otherwise it's likely the cam/crank sensor and the motor doesn't know what position it's in to fire.

​​​​​A trip to Nissan for a diagnostic can save you a lot of money rather than throwing parts at the engine.

Bump.

Did you ever figure out what it was? I'm having the same problem.

And I don't know why people keep saying take it to the dealer. I'd rather just throw money at possible causes and install it myself because even if it's not the problem, I know I have good parts now and I still spent half the money I would've spent just for the dealer to diagnose the problem, let alone fix it.

It's like $150 for a diagnostic, or you can replace.

Keys
Crank sensor
ECU
Coil Packs
NATS antenna
BCM
Miscellaneous wiring
Etc...

You still might not solve the problem either, or you can have the dealer plug in Consult-II, run the NATS diagnostic, run the ECU diagnostic, and they tell you what's wrong.

Then you decide how to proceed with repairs, either they do it, another shop does it, or you do it.
