Hello Everybody, I am working on an 08 350z for a good friend. I am a well seasoned mechanic, but this one seems to have me stumped. It has the security light flashing but goes off while cranking. While cranking, the tachometer does not move. I have checked for spark during cranking and it seems very weak. It has fuel, and fuel is present at the pressure regulator. Fuel is NOT present at the pressure test port. While cranking I have tried using starter fluid with no luck. I think I have listed all the things I have tried so far. I'm trying to stay away from the dealership if possible. Thanks in advance.
