The computer only commands the pump to prime though.

Orange - Constant power from PCM BATT fuse #3 15 amp
Gray - Power feed to pump
Green/White - PCM relay command, hot when initial prime and running.
Black/White - Constant ground
Red - Fuel Pump Prime Connector. There is a stray lead by the pcm in the harness that you can jump 12 volts to and force power to the pump. If the pump doesn't run then, you can be most certain it is bad. Only other issues would be bad ground at pump or break in the circuit to the pump or ground.
