Why wont my 98 ford f250 5.4l run, starts but will not run?

Asked by Jesse Aug 09, 2020 at 06:18 PM about the 1998 Ford F-250

Question type: Maintenance & Repair

My 98 ford f250 5.4l will start but wont run. When
this problem first began i was stopped at a stop
sign and it died. Started right back up and drove all
day. The next morning i go to start it and it will
crank but wont start. So i immediately took out the
fuel filter and blew through it and put it back in. It
started right up and drove for a few hours then
stranded me on side of road. Towed it to a friends
and changed fuel pump and fuel filter. It would
start but only run for a few minutes. I cut hole in
catalyic converters and cleaned them out. Still
same problem. Fuel regulator is good. Please help.
Im just a lady and i dont know anything about the
fuel systems or vaccum systems. And i really font
have the money to keep throwing into the only
vehicle i have.

Also after changing the fuel pump and fuel filter i hooked it to an OBD 2 and it said system to lean bank 1. I checked fuel pressure regulator and its good. But reset codes and truck still doing the same. No check engine light and now no codes.

A lean code can indicate a vacuum leak. How are the spark plugs? Some Fords have a fuel pump driver, yours could be bad if you have one.

It sounds like you have a clog in your fuel line, same thing happened to me when I changed fuel pumps I'd disconnect the fuel line at both ends and spray through with a an air compressor
