I have a 2009 370z With the EXACT same issue... with one exception.. Its the passengers side Camshaft position sensor that we can leave unplugged or turn it and the car will start and run immediately. BUT its in limp mode.
any help would be appreciated.
BTW... we already replaced both of the cam position sensors AND the Crank position sensor with new Nissan parts with the SAME problem after replacing sensors. Even Removed the clutch and reinstalled looking for a Crank sensor / Flywheel pickup issue.. NONE found.
???
