Sounds like the computer is 'dead'. With key on, look for a 5 volt reference (easiest to find on the throttle position sensor). i.e one of the wires going to TPS should have 5 volts on it. If no 5v reference then computer not alive. Next step would be to check the powers and grounds going to computer (you will need a wiring diagram).
This video will give you the testing procedures:
