Yes I am that desperate I will pay someone £50 if they can correctly diagnose the fault on my 1999 V Golf 1.9 Tdi 110 hp before I have to admit defeat and take it to the garage on Thursday.
The story is the car had a chunk out of one of the lobes and a hole in one of the hydraulic tappets which have both been replaced with genuine new parts.
The car ran before but was obviously noisey and lumpy.
The car now wont start it turns over but will not fire.
When I tried to align the engine to TDC to change the camshaft the flywheel pointer was around 2 teeth out with the camshaft locking plate in position and I could see no alignment marks on the injection pump.
I fitted the camshaft and a new timing belt aligned all of the marks correctly then took the injector pump cog off to find a u shaped cut out in the pump flange which I aligned with a pin to a hole in the injection pump body refitted the cog then made sure the pump bolts were central had the camshaft cog free then tensioned the belt and tightened the camshaft bolt.
I rotated the engine via the crank bolt 2 revolutions then rechecked and all marks still aligned and they did.
I think maybe the original timing belt had slipped as it was very loose probably not fitted tight enough as it had been recently replaced.
I have checked for fault codes via my Sykes Pickavant ACR4 and none are present.
I have performed a compression test and all read around 400psi.
The key immobiliser light and glow plug light both come on then go out as they should.
I cannot seem to get fuel to come through using my Mityvac so this maybe the problem but I also may have the injection pump timing wrong.
If someone is willing to come to Hull- East Yorkshire and can diagnose the fault I will pay them the £50 or if someone suggests the correct fault before it goes to the garage I will also be willing to pay them.
PLEASE HELP!!!

ok.... im not too sure what's causing the problem here, but im sure there is a user on here who lives nearby to you.

just a friendly word ;) we dont pay each other on here, we're all brothers and sisters, favour given is a favour owed. thats all. if you were near me, id do it for a pint of house best :beerchug:

i will try to find the thread where people posted their locations with vagcom and put it up here for you ;)

I am desperate so thought a cash reward might help get a response.
How would VAG COM be any different to my code reader?

Can you check if the engine shut-off solenoid is energised(stays open) when you turn ignition on ? If it not working, that might explain why you cannot get fuel trough the lines with the vacuum pump. If the pump jumped 1 teeth, then it wont fire. Had the same problem with my previous car. Could not get the marks aligned and found out that the timing is to be set static(by aligning the pump and flywhell to their coresponding marks), then dinamically, with the help of the TDI timing utility found in vag com. That works on cars with Bosch VE rotary pumps. If your engine is a PD, then the procedure is different. Have you bleed the system thoroughly ? The PD engines, have a tandem pump in the tank, check if its working by turning the ignition on and have someone listening for a faint whine around the filler cap. Can you provide the engine's code as i could find witch injection pump is fitted on your car, then we will be able to provide more solutions. Hope this helps. Regards, Chris.

The car has an AHF engine code.
I think its an early Tdi and not a PD
I have supplied the fuel cut off switch at the rear of the pump with 12V and you hear a click from it.
If I only knew that the injection pump was correctly timed then I am sure the car would start.
How do mechanically do this as I have set it to where I believe is the obvious position as a timing pin will only fit through the cog,pump flange and hole in pump.
How do you set the pump position if you fit a new pump there must be a way of doing it?

If your crank/cam timing is correct and its not starting, the static injection pump timing could be outside the ignition window.

When you use the pin to lock the pump, i think it is possible to insert it to one side of the correct hole, resulting it your injection timing being out by 30 degrees, resulting in a no start.

This TDIClub 'How To' is very useful for avoiding the pitfalls of changing VAG TDI belts:
