The module on the dist would be my first thing to look at and can be tested for free at most auto parts stores. also mice and other rodents tend to like to eat wires on unatended vehicals-might look around to see if any made a meal out of them.

SOURCE: fuel pump location 1988 ford econoline

Theres 2 pumps one in the tank, lift pump, and one in the chassis rail under the driver side. The one in the tank is cheap, the one in the rail is not. The one in the tank only produces low pressure to prime the main pump and if it is broken, may not cause that much of an issue except when starting. the one in the rail is a no-start if it fails. The idea is that the rail pump can supply high pressure for the injectors, so a fuel pressure test at the injector rail will determine which pump is playing up. Hope that helps Tim

SOURCE: 1991 FORD F-350 with a 460 cranks but wont start.

first hit the fuel tank with rubber mallet where you might think the pump is. it's best to do this with someone trying to start the truck. if the pump comes on, it is definitely the pump. you can also check at the relay look at the relay and it should show a diagrahm. jump the leads with the switch, not the coil, first check your fuses and check for power at the relay

You say you redid the whole fuel system which means what? From the sound of it the in line fuel filter may be blocked. If you replaced the pump this would be ruled out, if you were not in the tank the strainer on the pump may be blocked. Without knowing what "replacing the complete fuel system entailed" this is where I would start.
