Maybe if there are any local meets, you can make friends with locals who can help you as this will save both time and money over the trial and error method. I don't think anyone on here minds helping, but some things are just hard to diagnose if you aren't there actually seeing what's going on.

where i live the only diesel scene is f6squared which is me and my mates, im an active member of the local vw comunity, i know everyone there is to know but there all into gassers :roll: apart from us guys, theres no where to learn all this stuff apart from trial and error

if you can recomend a good book then ill giv it a go

Haven't read any books, but I did a lot of reading of the archives on this forum before I even got my Diesel, and it probably saved me many headaches, except when I missed the part about marking the throttle shaft before you take the linkage off. :oops: DOH!! Well at least you have a few friends there to help. I've had to learn everything by myself, so I have to check and double check everything before I do it. Hope you get the pump squared away soon. When you figure the problem out, be sure to let us know so that if it happens to someone else, we will have a better understanding of what was happening.

i didnt get chance to do any work today but instead i met up with rubadubdub (aka paul) realy nice extreamly helpfull guy, hes much smarter than me and so he found a load of realy good links and threads for me to look at. whilst looking through these i may hav found the problem, if sumone has anymore knowledge to offer.

ive removed and then reienstalled this shaft but didnt mark where it was before, can this be the problem as it sounds like this has sumthin to do with fueling from start up?

"The position of this shaft is important because it regulates the system of initial injection by vacuum (?). It's wise therefore, to mark the position of this shaft during pump disassembly"

can anyone explain exactly what is the "system of initial injection"?
and which way should i screw it to help me? or am i way off?

I don't know if it's just me or not, but I can't see your pics. If you are talking about the throttle shaft, going into the top of the pump, you do have to mark it or your engine will probably either run away or not start. If that is the one you are talking about, what i had to do was remove the springs and everything else from the shaft. Have someone sty to start the car while you have one hand ready to pull the wire on the fuel solenoid, and try slowly turning the shaft to give it more fuel with the other. If/when it starts and is close to idle, turn it off, put the throttle linkage on without the springs and without moving the shaft, putting it on as closely as you can to it's normal at rest position. Mark it, then put everything back together the way it should be. You may have to adjust the residual fuel screw, the one the linkage stops against, if the idle doesn't come back down when you rev the engine. If that isn't what you are talking about, then never mind.

im well aware of that, id just be happy if it started atall, the throttle may not be set up perfectly but ive been pumping the pedal so it should atleast giv me judder or a stutter, but ive been getting nothing,

the picture shows the shaft that goes through the govener wheel, aparently it must be in the right place or it cant produce enough vaccume for sum kind of initial injection? im confussed i dont know what this meens

Rich buddy,
did you look in the FAQ section there is a link to a pic. by pic. DIY to put a pump back together? sorry i can't help you you in over me head because i have not open up a pump on my own yet! I copyed it on paper incase i got some ambition! but that might help or see if you can find a good used pump till you figure out yours?
thanks Duane

I suggest that you are trying to run before you can walk with all the mods you are doing. No reason why you can't run in the future though :wink:
One easy way to check fueling sync with TDC on compression is to take off valve cover. Then losen nut on #1 injector. Get someone to crank engine acouple of seconds whilst watching for the diesel pulse. It should be easy to see it dribble when cam lobes are pointing upwards.

Always best to change one thing at a time from a known good position that way it is easy to take a step back IMO :idea:

maybe ur right, although the only new mod this time around is the pump piston & head, ive seen everything else work. ive seen all the picture diagrams ect, its not like i dont know how the pump works, i just cant seem to pin point why my set up doesnt work and its confusing the *** out of me, because in my mind it realy shud work

theres fuel coming out but its not firing up :roll:

surly thats not even possible? :?

Mark(The Miser)UK · « **Reply #25 on:** January 04, 2008, 08:21:49 am »

Just do that fuel squirt at the right time thing.... I assume you had the pump off when you changed parts so it may have happened then. Just 20 minutes graft :wink: Even if it only ticks another thing off the list. :!:

oldskool rich · « **Reply #26 on:** January 04, 2008, 07:36:50 pm »

i wanted to be 100% sure the timing wasnt 180 out so i took the pump apart again, turns out it was :roll:

put the pump together again will find out if it works tomorow, im posative it will work this time

ill tell you how it goes

she lives, it took a while and help from rubadubdub aka paul but we got it going and sounds better than ever before

the thottle response is amazing :shock: it sounds and acts totaly different from b4, loads better

it took a load of revolutions to prime it and we had nearly given up, i just kept fidling with the max fuel screw whilst paul carnked it over and eventualy it came to life very lumpy at first then gave a mighty roar as it over reved b4 we set it up, moved the pump until it sounded right (unable to use a gauge because its a 2005 tdi pump head) we have the wrong sleeve

only problem now is the oil light is constantly flashing and its not the sensor (tried 2 of them), any ideas? shud i change my oil pump?

also big thanx to paul, cudnt of done it without you mate :wink:
