2.25 diesel running rough, from bad to worse

I wrote this about a month ago on another post when I first had my issue of the truck feeling underpowered:

"It has been fussy on starting up in the am lately and suddenly the idle has dropped to where unless it's completely warmed up it wants to stall. Last night it was really bad. I had to heel-toe it at stop lights and even cornering to avoid cutting out completely because the idle was sooo low. I adjusted the idle today but overall the engine feels really odd. When I mash the gas at a standstill the engine takes a long time to rev up, and under acceleration it shimmys a bit. The exaust and the intake sound choppy like it's only breathing every other stroke. I'm thinking air and or fuel flow could be my problem."


Today I finally changed the fuel filter and followed the procedure to bleed the air out of the line. I tried to start it up and it wouldn't go. I tried bleeding more air and got some more, but still no start. Then I attempted the full bleed procedure as outlined in the manual by loosening the bolt (picture attached) on the pump assembly but no air or fuel came out, maybe a few drops of fuel indicating that it isn't completely clogged, but nothing like when I was bleeding the fuel filter. Still won't start.

Am I missing something silly or should I just try harder.

As always, thank you for any input.

Jeff

Try using a vacuum pump to bring the fuel up. Don't recall now whether or not you said you checked the lines from the tank were clear. Is there a shutoff solenoid on those or is it pull to stop like the old Series LR 2.25?

Crack open the last injector ( before the return line) and crank the starter till solid fuel sprays out. Tighten the injector and try again.

Crack each of lines to the injectors - one at a time. It bleeds air and let's you know fuel is getting to the injectors. Possible issues - injectors may need rebuilding, injection pump may need to be checked, mechanical fuel pump may need to be replaced, etc. But check simple (cheap) stuff first - fuel lines, filters, connections.

If you bleed the thing and after a little while you bleed it again and some air comes out you might have a problem with your fuel line. Once bleed it not suppose to have air anymore.. I would check all line first. Is the pick up pipe picking up air?

There's not many camel trophy trucks around. I just remember the whole Netherlands museum story, and what would be planned for it. quite the example you have on your hands...keep us updated!

absolutely, should be back from the shop with it's new engine and a/c by the end of january, next is putting in the floor (farmtek) for the roof rack and then slapping on the cb and deciding how to handle a radio for music. i was either going to go basic radio with iphone connector since i never listen to the radio or cd's or go with a rugged radio's system of headsets so i could talk to my passengers and listen to music without having to yell. decisions decisions

I might have to check all the lines. Before I even swapped fuel filters I loosened the banjo bolt on top of the fuel filter and got a little bit of air out. That might be my whole issue as to why it started to run rough.
