I have a 2000 focus with the Zetec that will not start. It has spark, but
no fuel, even at the input of the filter. I tried resetting the fuel
cutoff, checked the fuses and the fuel pump relay. I then dropped the tank
enough to access the fuel pump and I found a 5 wire connector going to the
pump, and another 3 wire connector going into the tank on the driver's side
(fuel level sensor?). I don't have a wiring diagram for this car, so I
need to know the function of the 5 wires?
Only 1 wire (white/red) has +12V when the key is in the run or start
position, but it also shows +12V after I remove the fuel pump fuse and
relay, so I doubt that it is the actual power for the pump. There are two
black wires (ground I assume?), a green/orange (I suspect fuel pump power?),
and what appears to be a brown/red(?).
If anyone could offer some suggestions, or a wiring diagram, it would be
