Fuel Pump circuit
Is anyone familiar with the electrical circuit for the fuel pump?
My pump failed the other day. The car started then just died and I couldn't start it again.
I checked the fuel rail and it had no pressure.
I checked the Fuel Pump fuse and it was fine.
I checked pin A15 from the ECU and it had +12V.
So then I pulled apart the back of my car to find that I don't have 12V at the connector to the fuel pump.
I assume there is a relay somewhere triggered by A15.
Anyone know where this relay is?

C404 is a light blue connector in the center of three connectors between the steering column and the under dash fuse box. The three sets of connectors close to one another are from left to right gray, light blue, light blue.
C401 is a large 22 pin gray connector located near the floorboard underneath the ECU.
The PGM-FI relay is a brown connector going into a relay box, it is barely visible underneath the nice little vent for your feet that is located under the driverside dash to the right of the steering column

Damn Justin, that is some good info. Thanks.
Chairman - Did you just reseat it? Or replace the relay?
