Ok, the path of power for your fule pump is as follows.
Power flows thru Fuse Link M (20 GA BL) and thru a fuel pump relay (Which is controlled by the Electronic Engine Control). It then flows thru an Inertia Switch. After that if you have duel tanks, it goes thru a fuel tank selector switch and to the pump. No duel tanks and just right to the pump. I would check to see if the fuel pump relay is letting power flow thru it. It should be located on the right hand fender apron, near the battery.

Suggested Repair

Trace fuel-pump power through fuse link M (20 GA BL), the EEC-controlled fuel pump relay on the right fender apron near the battery, and the inertia switch. If the van has dual tanks, also check the tank selector switch before the pump.

Conversation Summary

The owner of a 1989 Ford Econoline with a 351 engine reports no fuel from the pump and no voltage at the pump with the ignition on, and asks about a solenoid, fuse, fuse link, or short. The expert explains that power runs through fuse link M, a fuel pump relay controlled by the electronic engine control, an inertia switch, and a tank selector if dual tanks are fitted, then to the pump. They recommend checking whether the relay, located on the right fender apron near the battery, is passing power.
