Diesel Fuel Problems 6.9L Ford 1984

A 1984 Ford Truck equipped with a IH 6.9L diesel engine is smoking very badly. Fuel problems for sure. This video is a diagnostic step-by-step elimination of causes resulting in the conclusion that the injector pump is failing.

I didnt watch the whole vid but right after seeing it run i said " yep, needs a new pump ". I bought a remanufactured pump when mine went bad, it was $450 with the core charge. When they go bad they begin sucking air which makes a rough idle and white smoke.

Tom - Thanks for your comment. Turns out that there is a gasket inside the injector pump that gives out and degrades. The evidence is in the check valve. The IP needs to be rebuilt. I have sent mine in to be rebuilt and am waiting now to get it back. Thanks

Awsome video. I have heard many people talk about this, but never show it. I really want to buy this 85 6.9 f250, it runs great. This video helps me see what to look for or keep a look at. Thanks, you have no Idea how much it helps. Saved in favorites, and 5*.

Where did you send the injector pump for rebuild? I probably need to do the same.

[@dunn98632]

and fill your filer with diesel too helps on starting back up as well.

[@MrJumpcamp]

[@estalt957]

Diesel finally check up.

[@RobertEvanoffJr]

How much for the rebuild?

[@Jacksonkellyfreak]

sounds like hes sucking air into a line and losing prime

[@tpvalley]

how would a failing injection pump allow debris into the system? the fuel filter stops that. why would a blocked feed line cause smoke, wouldnt it just reduce fuelling or is it cavitation causing the pump to run retarded? I had same problem on different type of car, similar pump design (lucas,cav, stanadyne), seems they only run properly at idle if u advance the pump when they're failing but they then missfire at high load.

Well a gasket isnt to bad, so thats good but not good, lol. I think a new pump is like 500-600$. So hopfuly you wont be spending that much. But your welcome. I like vids like this.
