View Full Version : 2000 F250 haunting

March 5th, 2012, 12:58 PM
Have a mysterious problem with my Superduty F250 5.4 4X4 Auto that is pretty wild but probably an overlooked simple thing.
Runs and drives good, but for no "apparent" reason will start skipping and lose power and then die, no start. Turning the key on, at this time fuel pump doesn't cycle, no noise. When I check inside fuse/relay box, all seems ok, and shaking around under dash all of a sudden pump kicks back on and away it goes. I havn't plugged in a code reader yet and suppose that will be my next step. Was wondering if any owners have had the "mystery die out" happen?

Any info would be appreciated :smilez:

Im not sure if your year model has one
but there is a fuel switch located around the glove box that may be bad

have you checked the manual

Sounds like a bad fuel pump to me.

I had a similar problem with a 2000 F150 and it turned out to be the fuel pressure regulator. The fuel pressure was rising and falling as the regulator was failing and the engine would sputter and cough, or just die, and then would run fine for a while before doing it again.
