Re: No Pwr at testpoint on PCM
If you have pulled the relay and jumpered the socket to get power to the f/pump and it works sometimes and not, could be the pump itself or wiring. maybe unplugging and plugging the connector might help.
Next time the f/pump does not work, bang the tank to jump start the pump. One of the wires would be the same red wire from relay socket. If jumpered, you should have power there at tank. Another wire, if black, would be ground. Could be the terminal of this wire at body is heavily corroded and not making good contact to complete the circuit. The last wire, tan?, would be for fuel gauge.
