93 7.3 F-superduty

[Possum Creek]

Hi, oilburners I have been out enjoying my superduty hauling crossties and farm equipment with out any problems however after about a 200 mile trip yesterday this morning while shifting gears it died. It would start back up and idle and rev up fine but when I get off the throttle it will shut off like turning off the key. What do you all think? Lift pump? Kinked hose? Plugged filter? Any help would be appreiciated. PC

Are you running any fuel treatment? If not add some at double the regular amount. Sounds like the injection pump is gummed up.

i pour in a couple quarts of mercon ATF when i get the stall on deceleration.nothing else iv tried comes close to curing the issue like the trans fluid does.

Did you leave your truck at the shell station in Monteagle with a sign on the window about a fuel issue? If so, nice superduty.
Either way those were the symptoms I had when my lift pump quit. It would start and run, but died when you tried to move it.
To diagnose I pulled the outlet line from the lift pump and then had a friend turn the truck over. It should fill a pint jar in no time flat (I think if you search here it you can find the actual pump displacement.) Mine was just dribbling a little fuel.
As others have said, could also be stuck metering valve in the ip, but doesn't sound like a filter issue.
Good luck.
If that is your truck at the shell, pm me if you need tools. Its only a mile from my house.

Since the truck is setting, fill the fuel filter with Seafoam or another Additive, start er up let run for 3 minutes , shut offand leave set over nite, that will clean the IP inside, betcha your metering valve is sticking.
