Several possibilities here:
1. The PGM-II harness doesn't match the RC Valve servo (ensure that the wires at the connectors between the servo and harness correspond - if they don't, poke them out of the connector and re-arrange them to the correct pattern) as there are some wiring variations between models.
2. The servo is buggered, and that's what's caused the PGM-III to fail, which has in turn caused the PGM-II to fail! It's (nearly) always the RC Valve circuit inside the PGM that fails.
3. The RC Valve actuator cables are incorrectly assembled. One could be trying to open and the other trying to close! Don't dismiss it!!
There are other possibilities too, but explore the above first!
Quick check is to switch the ignition (and kill-switch) on and then disconnect the TPS on the carburettors. The RC Valves should open to the "setup" position. Tutn the ignition back off and reconnect the TPS. Switch the ignition on and you should see/hear the Valves return to the closed position.
If this doesn't happen, disconnect all the actuator cables and try again. If still nothing, double-check the wires at the connector between harness and servo match. Failing that, it's time for another PGM and/or servo.
