SOURCE: 1996 Ford F-350 460 gas engine. Stalls while going

I'd check the manual transfer valve on the dash. They have a tendency to go bad after awhile. Cause 1000 different symptoms, and be the last thing checked/replaced. It's probably the cheapest place to start. The pump under the driver's feet is usually the last one to go in my experience, but the secondary culprit is normally the main pump in the rear tank.

Next time it tries to stall, toggle the fuel switch and see what happens. Same with a hard start. Back and forth a few times quickly.

Hope this helps.

Testimonial: "thanks for the tip. Already replace this switch. "

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: fuel shutoff switch switch location on a 1988 ford

The fuel pump inertia switch that shuts off the pump in the case of an accident or impact is located under the right side of dash I have also
found them behind the right kick panel. There is also a fuel pump
shutoff relay under the hood on the left firewall, and a relay on the
right fender apron behind a plastic cover. Hope this helps.
