I would not be messing around with the pump. I do not believe the delivery valves is the problem here.

If you removed the 2 14mm hold down nuts and raised the barrel, the balance between the assemblies is now uneven. The pump will need to be removed and balanced on a stand. The only way to remove the delivery valve is to remove the delivery valve holder which requires the splined socket. Did you get a chance to mark the camshaft nose and see if it was indeed turning during cranking?

i plan on marking the camshaft nose tommorow.
I had a guy come over and tell me to lift the plunger then prying on it up he gets a call on phone that said i couldnt remove without socket tool.i should have just kept reading instead of asking just anybody to play with my motor.should have know by the heavy chrome wheels and no fuel guage he knew nothing.I just want to get my truck moving and making money again.
I lifted the delivery valve up about a quarter inch and put it back down again.It was the Dvalve closest to the gear case.i have cranked the engine over after doing this...

anybody got some pics or diagrams of the injection pump?

no it would not, this would not come into effect till the turbo starts to spool, would not have anything to do with starting or idle

heres a link to check if timing has slipped

good news is; the BOI will stay the same as he didnt do anythign witht eh shims below the barrel; bad news is that fueling may be unbalanced now. if the didnt rotate the barrel and lined up the old track marks he may be close enough to finish trouble shooting before he does have to have the pump put on the bench.

as for the owner; i know you'd like to get the truck running; but offering money to every yahoo can be a dangerous and expensive thing. so far you've experienced what this site is so good for... helpin eachother and most of the time the guys on here can get ya thru what you're workin on FREE.
