No power to fuel pump

Im looking for a wiring diagram for the fuel pump. I have no power at the pump and i checked the fuel injection fuse at the battery. Any ideas of what could be wrong, or help with a diagram would be awesome. Thanks in advance!

If you're talking about an 87ish through 93ish trucks then the fuel pump is controlled by the power relay located behind the right kick panel, under and next to the EEC. It is a black/blue wire, about 14ga., and runs from the relay to a fuel pump test outlet on the right inner fender, and ALSO down the right side of the floorboard to the connector under the passenger seat, then through the floor, accross a crossmember, to the fuel tank.
Hope this helps!

awesome thanks!!!!!! im gonna try to get her goin this week!

Looks like no power coming out of the relay on the blue and black wire. All the other wires are getting power and the relay is clicking, but that one wire has no juice. But another weird thing, i tried to attach a 12v wire to that wire (to try to get the fuel pump to cut on) and i still dont hear the fuel pump prime. It sounds like the relay is bad, but maybe the fuel pump too. What do you think?

This relay is an Engine Control relay and has other duties other than just the pump!
The EEC energizes the relay so if you hear it click then EEC is working. The Red, Black/White and Black/Yellow wires at the relay should be hot with key on. White/Red should only be hot for a couple of seconds after cycling the key on, then stay hot after the engine cranks.

I forgot, there is 1 more fuel pump connector under the dash, where the cabin harness plugs to the engine compartment harness. This plug only has 2 wires, the Black and the Black/Blue.

To verify the pump is good, I would unplug the connector under the pass seat going through the rubber grommet to the under side. Ground the Black wire and put 12v to the Black/Blue wire. The pump should run when you do this, if not the pump is bad or the connector at the pump has a prob...
