Can't get my 05 g35 rev-up to start. Here's the backstory of the car; I bought it for next to nothing after the previous owner tried to change the head gaskets, failed, and gave up. So i tore the motor back apart, replaced everything the po did, entire top end. Everything done according to the fsm. Went together fine, has compression, timing is right. Will crank all day long with not even a hint of trying to start, no spark, no injector pulse.
Now, the thing is I've never seen the car run, so i'm really starting from nothing here. I don't know if it died while driving, or if the head gaskets were even bad to begin with. No codes either.
Possible causes: crank angle sensor, flywheel installed wrong, bad ecu, security problem. Anything else?
I've read a million threads about security problems with these cars. Seems like it's very common. Everyone says the security light will stay on if it's a problem. Mine never comes on at all, so i don't even know if the light works. The car also has an aftermarket replacement key. So that whole situation is a mess in itself.
My question is, is there anyway to know for fact whether it's a security issue? I'd really hate to tow this thing to the dealer for them to tell me it's fine.
Thanks in advance

 

If your security indicator doesn't turn on EVER then you likely have an immobilizer problem. I would buy a sandwich adapter so you can check fuel pressure to rule it out as well as a cheap crank sensor. Personally I would pull the transmission and check the flywheel alignment because like you said you have never seen the car running.

If all those items check out tow it to Nissan for a diagnostic or purchase Nissan Datascan II and program the key for yourself to rule out it's not just a key issue, you will need the BCM decoded to get the PIN number for it, there are internet services available for this.

 

Thanks for the reply. I actually got it figured out. There's a ground in the harness that looks like it got ripped out. Soldered a new wire in and she starts up perfectly.
