Engine will not fire after Inj Pump rebuild??
hey brusier, in case you wanted to know i found a pic of the pump part my brother installed wrong.http://www.cs.rochester.edu/u/jag/vw...i/injpump.html
Thanks those are some good pics
Well I went to shop an tore front end apart and I think I found my problem..
The woodruff key was missing..
It fell out onto cross member when we took timing cover off..
So we 1st checked all the gears and I am very very lucky al lthe teeth are still on gears with no marks or broken teeth..
what we found out was someone has been inside this engine before..
reason you ask??
the woodruff key is the incorrect size.. it is to small so when we put it backin only about 1/16th of it was in gear side and rest was in shaft side.. that is not very much holding it there. so I went to NAPA and found one size width but tall so there is now only 1/16th not covered with the key...
hope that makes sense..
so I did not get it al lback together tonight but I am going to try to get it finished and see if it fires tomorrow night. so if all goes well I wil be driving truck again soon..
I will keep ya updated..
Thanks for all the advise and help

Well of course if it not one thing it is another..
I worked at shop again and I can get gear onto ij pump shaft with new woodruff key on but it is off 2 teeth from where it need to be for TDC
I am not sure what I am doing wrong on this.." but dang my brain is working to dang hard on the weekends
"
Question: how much play should there be in inj pump when all bolts are loose.. hould I be able to rotate pump which will rotate pump shaft so the gear and teeth line up correctly??

If you still have the lines on.. its can be a pain to rotate the pump... If you have the gear in, turn the engine over until the gear lines up with the pump... On the key.. I take the key and lay the key on one side.. hit it with a center punch, so it has a small dimple.. then put it in the shaft.. this will hold the key in the shaft... (I'm sure you already did.. but don't forget to move the timing pin to the out position..)
You'll get it...

(As long as you have the pump gear in the correct location when you install the gear.. it doesn't matter where the key is when you install the pump.. I turn the engine over until the key is in the 12 position.. so its easy to keep in. .and I can see it go into the gear.. )

I can't see any reason why you couldn't turn the pump with you hand......unless the pump is still pinned????
Thanks for info.. I got entire thing back together.. I had to lossen a bunch more things to get it all lined up but i got it..
so hopefully tomorrow i can get a new banjo bolt that i broke and fire it up..

All I can say is I am just slam wore out....Thi is driving me nuts..
Well we got banjo bolt on bleed entire system and truck still will not fire..
short version: I took engine complete back apart and found out that the first woodruff key did do some damage.. it creased the seal on inj pump shaft so some diesel was leaking into timing cover area
so off comes the pump to be sent back to be rebuilt for a 2nd time
but while doing this i was very conserned that the pump timing is off. so i took off bolt that holds the alignment key on and looked inside it.. what i found was you can see the inj pump shaft and if you rotate this there is a black mark on that shaft.
Question: when that black mark is lined up with the hole where should the wood ruff key be facing.. shoul dit be at 6pm ish or not..
mine looks more like when the black mark is lined up with hole it is about 430ish...
this is in association to the truck being set at TDC..

Ok the first pic, is the pin the locks the pump that wasn't the bandjo bolt that you were whating for.......right?
any ways that bolt will be in all the way to lock the pump in time when you get it back.
after you have installed the the pump back into the the gear and tight the pump bolts.....then that bolt in the pitcher must be remove to put some washer or that lever looking thing back in so as to keep the bolt from pressing on the pump shaft!

but if you take that bolt of there is a black mark on the shaft if you look inside the bolt hole with bolt out..
I need to find out if that black mark should be shwoing when pump is timed or not??
just put the pump in the gear,thru the slot and bolted it up. look at the timing mark,sean that it was in the same place as before,remove bolt anded spacer and retighted the bolt up.I'm shore that when you get it back this time, it will go a lot smother.
Don't for get to change the fuel deluted oil too.
Honestly i never look inside the hole before
