Shaggies new AAZ engine wont start - Any ideas??

[shaggy]

Hi Guys.

Well I bought a new AAZ engine for my passat B4 due to the old one havin a well cracked cyl head. Ive fitted the new one & its all spanking clean. Ive been trying to start it and it turns over fine but wont fire. There is fuel going into the pump and back to the fuel filter thro' the return but it isnt coming thro' to the injectors. I can see the fuel (and air bubbles) passing through the inlet and return pipes, however when I crack open the injector pipe(s) there is no fuel comming throught them. Could this be a faulty fuel cut off valve? Am I correct in thinking that if I disconect the fuel cut off valve then the engine should fire - that is if the fuel cut off valve is the problem??? Also - Is the fuel cut off valve the black box located just above the injector outlet pipes on the injector pump. Thanks, Shaggy.
