I have an 03 turbod 350z. It won’t start anymore it will crank but won’t start it has fuel pressure. When I turn the key to the on position the fans turn on high and I can not get any obd2 scanner to connect and I’ve heard that those could be signs of a bad ecu. There are wires coming from the crank sensor that scraped the ground and that is what I think would have caused it. I have since relocated the wires and changed the crank and both cam sensors

 

Could be , but if you had a short, check all the fuses

 

checked all of them and they were good
