I recently changed my motor in my 05 350z. And now my motor won't turn over. I don't hear the starter even trying to turn. Another thing is that the wire harness that was stock doesn't fit to the starter, so I bought a starter extension wire and hooked that up from the alternator harness to the starter. The car was throwing codes p1122. I changed the throttle body sensor plug from the motor I took out because I know that one was working. But I'm not sure what it could be . Any help???
