i tried taking off one of the delivery valves and then was told i need to take something else out to take it out.i am not sure what kind of wrench i need?anybody know what it is?

was also told about vacuum line next to intake manifold and afc being made of plastic and leaking...?anyone heard of this?

the truck was running fine once started ,but was taking longer than normal to start,never died on me.ran for 30 minutes on highway and when parked havent gotten it started since.been over two weeks now......uhg

i put the new overflow valve in and when i prime it the pressure goes up to 30 psi and wont go back down until i stop priming.....before it would climb to 22 and then release.

any websites about taking apart and rebuilding injector pumps would be appreciated! -

Delivery valve removal requires a special splined socket.

Forget about doing the Injector pump yourself. This is not changing a tire - its specialzed work and you want someone with experience working on it. Some things are best left to the experts. -

its actually a boost line that goes from the mani to the afc which regulates fueling in relation to boost. don't think thats your problem tho.

If thier is a leak in the line that goes from the afc to the intake manifold could it cause a problem?

i tried taking out one of the delivery valves without removing the part that you take a socket to get the middle part out.I got it about a quarter of an inch up.i put it back in and it seemed to seat fine.DID i just screw the pump or delivery valve?Is it possible to help the delivery valve if something is gumming them up by doing that?

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? -

oh oh...now you can have the pump looked at to see if it was the problem or not. -

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. -
