Hello all

Im new to the forum so bare with me if my questions seem a bit silly. But anyway my van indeed died during acceleration i had about 70km/h speed and went on to switch for the fifth gear and car just died.
I had driven car for about 5-6kms and engine was quite warm as my friend had just borroved the van before.
There was also the insidence previous week when i ran out of diesel as i forgot to refuel the van in a hurry.
When i ran out of the fuel i did fill 18liters of diesel and she started right up without any problems(i had to crank the van three four times but anyway).
When the van died i had about 1/4tank of diesel in it, and i have since filled another 18liters on it just in case.

But back to the current situation so currently the car:
-cranks nicely.
-glow plug light comes on for a few seconds when try to start in the morning.
-no fault codes with vag-com eng/immo.
-no fuel to the injectors.
-new fuel filter+that plastic connector that goes on top fitted and feed pipe blown with compressed air.
-tried to feed shutoff solenoid straight from battery no help.
-Injection pump timing belt felt really loose and timing might be off will check tomorrow

But does that explain no fuel to injectors, does ecu cut off the fuel if the timing is off and wouldn't it trigger a fault code?

Any help would be greatly appreciated. If someone would have wiring for the ecu and injection pump that would be great, i would like check the wiring harness.

if the injection pump belt is loose it wont be spinning the pump correctly so no fuel or very little will pass.
If the belt is loose at all then that's bad and would be the reason for the van stopping, hopefully It is just the injection pump belt but you should check the timing belt also, remove the 2 spring clips on the cover and slide it upwards, this should be tight also with no play

Hi geeo

I'we checked the timing belt and that seems fine. The injectionpump toothed belt does rotate the pump but has too much slack imo. Luckinly i have bought the dial indicator for pump timing so i will chek it tomorrow. Just have never worked on diesels before and therefore i am littlebit lost. But i still don't get it why there isn't fuel to injectors because the pump is turning when engine is cranked. How loud click should there be in the solenoid when it is energized? because mine only makes quite small click when ignition is switched on.

the click isn't that loud and you can check it is working fine with a multimeter, the belt is loose for a reason I would find out what that reason is and fix it first it would be a bit unlucky and coincidental for it to be both the belt and another problem at the same time

You are absolutely right geeo!
Today i started to check the injection timing properly and found that it was slightly out according to marks on pump and pulley, So i went ahead and installed my dial gauge to pump and loosend the cam side pulley also the engine was 100% sure on TDC.
Then i did like vw instrunctions said and i put 2mm of preload to indicator and started rotating pump first counterclokwise nothing on the needle then clokwise also nothing on the needle.
Basicly you can turn the pump as much as you like and the needle wont move, So either my ebay kit is somehow not working with the pump or the pump itself is kaput, wich would explain the no fuel to injectors.
Tomorrow i will pull out the pump to have a closer look. And also replace the water pump and timing belt because i already have the kit for it just hadn't got around changing it before.

Okay

Little update!!

Today i pulled off the injection pump and found that three of the four highpressure pump bolts had sheared off.
I gave a pump specialist a call and he tought one of the hihgpressure pistons had seized and caused the bolts to shear.
So i found a reconditioned unit from ebay for 399eur so now it just waiting to get the new pump, Should arrive end of the next week.
Meanwhile i planned to replace the timing belt water pump and some oil seals like cam seals and valve cover seal, So after all this hopefully it's just a matter of installing a new unit timing it and then back on the road(and yes i will do the static and dynamic timing).
I tried to look inside the injectors and pipes i couldnt see any metal shavings so i will leave them as they are. New filter is already installed with new fuel heater connector, also i will change the injector overflow lines as they seem quite deteorated. Any ideas what should i check /replace while i have the car in bits the auxilary belt tensioner and roller are fine aswell as the balancer or what the heck its called that big pulley that lives on the end of crankshaft(i will fit new bolt thou) but don't know how the heck to torque it to 460Nm i quess i will just use my windygun as i remeber it puts out around 500Nm clockwise.
