I have a 2004 Infiniti g35 no crank no start but I can hear the starter turning(already took it off and checked it) engine is not seized I turn my crankshaft pulley with my ratchet turns perfectly fine changed my crankshaft position sensor and both cam shaft but bank 2 is not a oem when I’m trying to turn it on I got code po345 now I’m lost because it won’t turn over

 

Only use OEM Genuine Nissan Parts, or Hitachi sensors. Hitachi was the OEM manufacturer for most of the sensors on the car.

P0345, cam sensor bank 2 is bad.

You say "no crank no start" but then immediately said you can hear the starter cranking the motor??? Which is it, either it won't crank, or it will crank.

Also keep in mind that cranking the motor takes a LOT of power and you can quickly discharge your battery by cranking without starting the engine, put a charger on the battery to top it off.

 

yeah what’s happening is I can hear the starter engaging but it’s not turning over but I’m the engine is not seized because I can turn the crankshaft pulley with a ratchet if it’s a faulty wire where should I check

 

Ahh that's a dead battery or weak/failing starter. Start with a battery charger and see if the battery will take more juice.

If it is fully charged and you're still just getting it to engage but not turn the engine then remove and bench test the starter.

While you're charging the battery that's a good time to clean up the battery posts and the cable lugs with a metal brush to make sure it's a solid electrical connection.
