right, i switched my cam plate 180 timed with the all the tools execept the gauge, IT JUST WONT START! not even close, it smokes, but doesnt juder or splutter what so ever
i thort i may have over torqued injectors, so i torqued up an old aaz injector to about 100 and conected it to a fuel line, it pumper out plenty of fuel. it doesnt make any sence,
my last hope is to use a timing gauge but that wont tell me if im 180 out will it?
im so pissed off with it, and i desperatly need my truck on the road quick time, its the 3rd engine its had, never had any trouble untill now.
please any ideas will be much apreciated
i know its not the compression or anything like that, cus i had it workin off my abortion of a mtdi pump. im at my witts end
if anyone is a pro that lives in or near cov id be happy to pay you if you can fix it

your first hope should always be to use a timing gauge. eyeballing might get the engine running, but running like crap. even if the pump is out it will start, but as Tintin stated in the previous thread, it will run like crap and have little to no power, and probably smoke bad.

I couldn't get my rabbit started (The battery kept dying) so I got towed down the block (not fast at all) and about a half block down the road, she was running like a champ.
But, I agree with the above, it won't start when the timing is out.

who put the pump together? What all did you change from the running to not running situation?

id just be happy if it wud run like crap tbh, i tried towing it for about 2 miles, still not even a splutter
it worked like crap and off a tow start wen i was running the tdi cam plate, all ive done is swap back to my aaz plate, now it wont start at all, but that makes no sence to me, surly if there is fuel cuming out it should be running

there is only a small window (1.00mm +- 0.20mm) so if you think about it, without the timing gauge its easy for it not to start.... just get yourself the timing gauge already!!!

I had the same problem when I put my pump back together.
Things to make sure of:
-power to glow plugs
-pump has prime
-Air bled at injector lines
-Pump in rough time
Since you had the pump apart I am assuming you had the throttle(governor) assembly apart. If all the rest is good then it is very likely the throttle lever is slightly off (this is what happened to me). The lever only has a few degrees of travel and if it is slightly off the car won't start or will run-away.
This adjustment takes a bit of trial and error. Mine went from non running (but blowing smoke) to running away as soon as it would kick over until I got it right. There should be a scribe mark bi-secting the end of the trottle shaft that you can use for reference. It can be frustrating so if you have to do it make sure it's with a fresh mind.
Let us know what it ends up being so it can be added to "the list" of no-start issues.

ok ive done all those things, but still cant get hold of a gauge untill next week, wen u say govener, u meen the wheel with the fly weights and the little bar sticking out the middle, that fell apart and i dont know if it went back together properly, can i just take that wheel off all togeather, cus ive done the govener mod anyway, maybe its that thats not letting the control sleve move, it doesnt do anything else apart from being a limiter does it?
if this isnt what u meen, can u dumb it down for me, i dont know what things are called :cry:

The drive pin in the came plate must be aligned with the keyway on the shaft pump, where you bolt the timing belt pulley, like somebody said to you in your other post.
You really tested to turned the fuel screw 1 turn at a time until the motor finally start, screw it at the max if you need.
I'm do not remember exactly, but 1 turn on the fuel screw = 0.20mm on the plunger control sleeve, would be need that I look in my book notes in my garage.
edit: I suspect your ground plunger which do not have the good position on the cam, and you sure that is a right turn plunger?

ok the plunger is off an AFN, like i said, it worked like *** with the tdi cam plate, ok now i understand what you meen by "keyway" ill have to take it apart again to check that out :roll: ,
here is sum pics of the dona pump
it turns the same way as the aaz pump unless the afn spins backwards, which i doubt :?
to eliminate the governer can i just take that whole wheel and fly weight thing out?

I was talking about the splined accelerator shaft that the throttle arm and accelerator cable attach to that actually manipulates the control sleve. If it is off by a couple splines it will give too much or not enough fuel.
I hadn't realized about the level of modifications that you had done though so there may be more to your problem.

i wouldn't take the governor out... it's a good safety device. without it the engine might just rev to hell and blow up :shock:

my govener mod is a load of washers instead of a spring, i have a rev counter with shift light instead so that wheel serves no purpose.
btw how much max rpm can my engine take safley?
im gona take it all apart one last time if it doent work i will go back to a standard pump :roll:

It sounds like you really need to learn a lot about Diesels before you start messing with anything, otherwise you are probably going to end up destroying your engine. You need to fully understand the engine, what mods are possible, and what the mods do, and it sounds like you don't really know any of it. If I were you, I'd take your truck somewhere, get it fixed and then do an awful lot of reading.

im sorry if im wasting everyones time with stupid questions
i know i have much to learn but ive already leaned so much off here
ill get there in the end, i do appreciate everyones help
