Diagnostic lights not working

Hey guys, thanks for the help in how to do ECU diagnostics. One little problem - I turn the key on, turn the knob on the computer clockwise, wait 3 secs, turn it back - then nothing happens.... did this bout 20 times, nothing worked - exhaust smells like ass, a/c fan constantly on - Any clues?! Thanks

Re: Diagnostic lights not working

Sounds like maybe the ECU is bad, have ou recently upgraded the chip and perhaps put it in backwards.

Check in at www.300zxclub.com we use this site mainly for FAQ's and backup.
