I have a 92 3000GT SL and the computer is in some kind of lockout mode and won't communicate with anything. It runs and idles about 2500 rpms and the electric fans don't kick on anymore. Anyone got an idea? Guessing i need another ECU but let me know.

 

Well first off your in the wrong section lol, but anyways check the powers and ground to the pcm if they are ok and you still cant communicate I would replace the ecu.
