I did everything right on mine, and it wound up being that my timing slipped WAY slow. I'd give that a try. and post in your regional section offering BBQ and beer, not cash.

 

took off solonoid arm and have manually lifted the shutoff valve.had someone hold while cranking and STILL no fuel coming out from delivery valves.

talked to another 12 valve owner and said something about a vacuum line being cracked around afc that alows fuel to get to injection pump...a governor that works on vacuum of some sort.

at any rate looks like i need to do more reading.these things just seems way to fickle.got an 84 mercedes with 315k on it and starts in a second when cold(still pretty warm in FL though).the ctd used to start really fast too,the a few weeks ago got longer and longer to crank.till finally after have a really nice strong ride....not starting.

this has crossed my mind too.although it ran strong the last time it ran.I ran it down the highway too and i ran it for about a half hour.i did the KDP mod in the first few months i got the truck and i never checked the injector pump nut/bolt/screw?.it looks like the previous owner didnt do anything but oil changes to this truck.

 

what did it do, or what did u do to it just before it died. were u driving and it quit, or were u adding stuff to it and it quit then, or did u just shut it off and it quit? good luck figurin it out

 

Have you checked for spraying fuel at the injectors?

Have you been into the tank at all?

How much fuel do you have in the tank? Im thinking you should have at least 5 gallons.

 

from reafing ur other thread now, if u had gunk in ur tank from the bio when u dropped it, u might have a DV sticking from the bio. idk if thats possible, but worth a check to see

 

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.

 

you can change the DVs but anything more than that i wouldnt get into

 

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?
