Your right but the p-pump is really not a challenge. From what I've read and heard only a few are making 500+ hp on fuel only. This would be something I'd like to play with for a near/far future project. Keeps me occupied and out of trouble. I love to play around with MY stuff on my time. If I don't tinker with something my idle hands gets my active imagination in trouble. I can go in shop in a foul mood and tinker on my stuff and I get right in the head lol. I love challenges and even tho it cost $$$ it saves me money. If I don't spend it on a project I might start drinking or who knows what. Maybe i have adult ADHD lol. Well i need to get the injection lines on and see if I did this right!

 

Ok got the pump on and bled the lines until fuel was flowing all over. Hooked up the lines to the injectors but left them loose and bled somemore until fuel was spraying all over. Tightened down 4 of the lines and attempted to start "wouldn't fire". Rechecked the throttle index and was off one mark but still wouldn't fire. Screwed in fuel screw and it fired but barely ran. I broke the "cardinal rule" didn't count the turns when I removed it for the pump repair. It has a modified fuel screw in it-it's been welded on to make it longer. I'm leary of screwing much more for the fear of runaway, "been there done that on a 8v71" lesson learned. Ok any rule of thumb about how to set/adjust the fuel screw-depth ect. Help me here pump guys!!!!!

 

The index is a very very fine tune, even if it's moved a hair off it will prevent the truck from running. To reset it back to normal, index it at 1 1/2; back the fuel screw all the way out and take a clean nail or metal wire and insert it into the hole where the fuel screw was. You'll come into contact with a lever. Measure the distance to the fuel screw and thread the screw in that far. Turn the fuel screw 1/8 turn and attempt to start the truck. Depending if you screwed the fuel screw in all the way I would get a small block of wood in case the truck does run away.

Make sure all the lines are air free, actuate the lift pump until it's firm and crack the lines one by one. Did you line up the cam rollers inside the pump to the keyway on the shaft?

 

Thanks! Yea I lined the cam pin to the keyway on the shaft, only after i disassemble it a second time. Alot to "tune in" after pump replacement on these ole rides. Banner I thank you very much for looking out for me! Time to get started!

 

Ok banner new question! Ok ok another new question lol!! No luck starting truck. I kept turning in fuel screw and finally got it to crank but just barely runs at wide open "runs like at idle". Pulled top off pump and manually pulled lever forward till it wouldn't go any farther and cranked it again with same results. Man oh man I made a mess! Any ideas???

 

Whats the indexing at? If it was running then you need to adjust the indexing. Typically 1 1/2 or the second notch is what makes it run. You have to be right on the button.

 

I've indexed the throttle shaft seven ways to Sunday, the thing that bothers me that in order to get it to run I have to screw the full fuel screw in ALL the way in plus hold the throttle lever wide open then it might only rev 900 rpm's. I've gone over everything I've done and can't come with anything wrong. Lol this is frustrating but a challenge. Any ideas? Check your PM

 

No pm, it has to be the indexing if it's running at WOT. How are you turning it? Take the pump hat off and you'll see the gov spring there. It all needs to be in a straight line. If you turn the shaft one rotation.. its going to gum up that spring.

 

Ok I tried everything but no luck. Pulled pump off and tore it back down. On my pump the control sleeve is cut square on one side and the other had a chamfered cut. That was the only thing I found. Turned the control sleeve around reinstalled pump and bled the air from pump and injector lines. My bleeding process was different somewhat. As I installed the injection lines I used my handy dandy mighty vac tool and injected diesel from the injector side towards the pump and bled at the pump. Worked pretty good. Fired the truck up and it runs pretty good. Going to tune on it and play with the AFC probably tomorrow. I think the auto trans will be next, with extra power or the power it has I can make it slip under HARD acceleration or it seems to be slipping. Thanks to all that chimed in ideas on my ole ride.

 

Glad you finally got it going good work!

 

Thanks Bill! I have really appreciated everyone's help! I would have never figured this out if I hadn't taken notes and pics! Was ready to go to the pump shop. But I had laid it all out in order with notes & pics so I was confident I had it right "almost". Never dreamed the control sleeve that had maybe 20/1000's chamfer would/could make a difference. The pics that I went back and looked at online didn't show a chamfer, well only one in a vw pump. Live and learn and I learned alot! Appreciate the help/ideas guys and again thanks!!
