I did some engine repair and after putting all together - it is not starting! I believe that all the camshaft and crankshaft and fuel pump timing is correct as I uses special tools for positioning them!
My suspicion is fuel injection pump as disconnecting one of hoses coming from pump to injector there was no pressure at all - while cranking engine there was only few drops coming out as I suppose should be high pressure spray!

What could be possible fault?
I am new to all these thing and want to learn and do not be mean if I ask some stupid question like how can I find fuel pump relay among all the other relays as it could be possible reason for the problem! I do not have a manual and I do not have Vagcom tools!

It seems more like electrical problem rather than mechanical as there is no problem with fuel line to the pump and pump gets the fuel from fuel filter! Just there is no pressure generated in the pump!

Hope someone can help me with advice!

About all I know about these new diesels is to be very careful with high pressure lines...
It seems you need to get a service manual (Bentley or CD version/eBahn) and perhaps a vag-com to find out what's going on.

I know and we will try to get Vagcom tools!

This is direct injection or whatever it's called for my audi model!

It's not common rail injection which I have heard is even more complicated!

I just wanted to know how can I identify which is injection pump relay?

Cause I read in other forums that these symptoms might be cause by faulty realy!
