Expert Fuel Pump Opinions Needed!
Just got a 2002 Tioga 24D. Base is a Ford e350 Super Duty van. Will turn over strong, but starts for only an instant. With the help of Starting Fluid, will run for several instants. Zero pressure ...

And he's assuming that one could pull fuel through the dead pump as well. BTW, pulling fuel doesn't work near as well as pushing fuel, hence the reason electric pumps are generally located at the source (in the tank).
A well intentioned suggestion, but OP hasn't even responded. Either the pump runs (makes noise) or doesn't. Presume doesn't but he hasn't confirmed. And if it does and aint pumping fuel, then its still shot, but at least can be diagnosed as the pump and not something upstream in the power supply.
Poster may have assumed it will pull, don't know, but I suspect the poster that mentioned using an external pump was to help diagnose the issue. Well intentioned but doesn't prove that 1, the ECM is good, 2 the wiring to the pump is good, 3 pump is good..
All three must be good for OP to get fuel pressure at the rails.
As far as hearing the pump run, generally you will never hear them run as the more modern electric pumps are not loud and don't sound like a grinder any more..
Was doing some research, on 2002 Ford pickups there is a fuel pump module that was mounted at the rear of the truck above the spare tire.. Not sure if the vans are setup that way.. But worth a look see to verify that all the connectors are in good condition.
I had a 2003 F250 with 5.4 and a few other yrs of 5.4 engines and am familiar with them.. Never had fuel pump issue but did have intermittent fuel gauge issue on the 2003..
