Fuel pump power supply
Fuel pump wiring diagram anyone?
i just replaced my fuel pump, and installed a Walbro. But I have not been able to figure out why I'm not getting my fuel pump to run. It wasn't working before, I've checked all fuses and reboot eyed the ECM but there seems to be no power to the pump. What do I do next?

do you have power?
the ecu sends a ground to start the pump

Not sure how to check. But I hooked pump to 12 volt source and got pump to run. How do I check the ecu power? Could it be my regulator.

Thanks! You were absolutely correct! The problem is at the connector to the ECU for the ground. Suggestions on fixing the connection?
