Good point. But which other inputs are required? Harness was modified so that clutch switch , trans switch are bypassed. My main issue is none of the wiring diagrams are correct for my engine. I have just found a manual for an AUS spec 2.2 1994, and the plugs are the same , but the wires are completely different.

I have an EJ22 94 in a beach buggy. Engine coughed a few times. Once stopped it would not start. Fuel pump does not activate. OB1 electronics. Earthed solenoid and the fuel pump worked, still no start. ECUs are getting very rare so bought a re-conditioned one at great cost. Installed and no change. Checked power and earths to the ECU , all OK. Connected green plugs , and pump does not turn on. The supplier claims the ECU was tested and OK, but this sounds to me like an ECU failure. Can anyone help with any more ideas?
