the other day my 2004 Sport Trac died while i was driving down the road.
i towed it to the house, and determined the fuel pump was bad by:
1) listening to the tank (no buzzing when key is turned to run)
2) checked the fuel pump fuse, still good
3) checked the relay connections for power, got 1 always hot... 1 hot with key in run position
4)checked for power on the female connection and got battery voltage on 2 wires y/wh and gr/pk
5)replaced fuel pump and filter and still no buzzing when key is turned in run position
6)replaced new fuel pump with a newer fuel pump... to no avail
i guess my two questions are 1)what else should i check and 2) what are the y/wh and gr/pk wires for? haynes doesnt have a wiring diagram for it(go figure right)
... any help would be appreciated!
