Hey fellas-

First post on here. Thanks for making this forum happen. It looks rad.

Five years after my 1984 Ford F-250 4x4 with 6.9 diesel died (after 250,000 of hard logging road miles), I just picked up a 1985 Ford E-350 van with a 6.9 in it as a Baja surf wagon. The thing ran awesome for 2,000 miles up until about an hour ago when I changed the oil and then the fuel filter. After the new filter was on (like a dumbass, I didn't have any clean fuel on hand and didn't fill the filter up), the thing fired right up, ran for 15 seconds and then died. Having swapped fuel filters like 50 times on my old truck, I got my gal to turn over the engine while I bled the shrader valve above the fuel filter. Nothing. Tried a few more times. Nothing. Not a spurt not any pressure at all. So I pulled the new filter off, siphoned some fuel into it from the back tank and tried again. Nothing. Not a spurt of air or fuel from the schrader. So I cracked an injector. Turned the thing over myself 10 times. Nothing.

Y'all have any thoughts before I start rebuilding this fuel system from the pump up?

Many thanks in advance-

Mick

 

Sounds like an air lock somewhere, i think holding open the schrader valve there is just letting it pull more air into the system.

honestly, the best thing to do would be to add an electric pump down by the tank inline somewhere so it can prime the system for you. I killed an electric once and switched over to the still working mechanical pump and couldn't get it to prime enough after an hour of cranking and having lines open etc... so i gave up and stuck another borrowed electric pump back on and it fired up after a few seconds.
