I am sorry, but "thinking" you have power to the relays does not do me much good. Let's do it this way.
One of the relays of the four will have the following color wires. My diagram does not tell me which one for sure, but look for these colors. These are the wires going to the relay socket.
1- Yellow-12 volts from the fuse. No power, the fuse is out.
2- Dark green/yellow-power to inertia switch. From inertia switch to fuel tank selection switch, then to fuel pumps.
3- Red-12 volts from computer when key in "start"position. Not "run", start position.
4 Blue/orange-ground from computer with key in "start" position.
Test; jumper wires 1 and 2. You should now have power to the inertia switch, the sector switch and which ever tank is selected, that pump should be running.
If not, check power at fuel pump connection at tank. If you have power there, the pump is bad.
