2003 Ford Ex. Cranks but won’t run.

Diagnosis do far:

1. Cranks and will fire with starter fluid but won’t run on its own.

2)No fuel is getting to the fuel rail. Originally some residual pressure there but none now.

3. Fuel filter replaced. Emergency fuel shut off function reset. When car is turned on, the fuel pump can be heard to cut on but it does not reach rail nor does fuel reach the newly installed fuel filter.

4. Affirmed no fuel flow to filter by disconnecting fuel feed: Turn on car, fuel pump whirs but no flow.

5. Next step: Pull fuel tank off, remove fuel pump, inspect pump and filter screen “sock” on fuel pump.

QUESTION: I’m told that on this Ford model, the “sock” alone can not be replaced and thus a whole new fuel pump will be needed?

Can anyone confirm that for me or suggest any other possible fixit here?

Fuel pump probably should be replaced anyway. Probably overdue.

Additional info/hint: This problem started after I bought lowest grade gas (87 octane, with ethanol) from a country store, apparently got bad gas from bottom of THEIR tank.

I’ll start pulling the car tank later today, since–as I’m told–you can’t drain tank on that model Ford Ex.

This seems to me to be logical next step, given diagnosis steps already taken.

Thanks to all for prior comments here. Any further comments, suggestions welcome!
