aaz injector pump

[strat1]

The aaz which i have fitted to my camper doesnt seem to be pumping any fuel, it is connected straight to the fuel filter. Is there supposed to be a secondary fuel pump? My old jx was self priming and connected this way.

I can hear the stop solenoid clicking so don't think it is that, anyone any ideas?
also the flywheel timing is not accurate with the pump and cam, i was hoping to see the no 1 piston when I took out the injector but it is not visible, is there another way I can get no1 on tdc?

i took no1 heater plug out turned engine at crank testing with a welding rod to see when at tdc then locked pump and camshaft to aceive timming it runs ok but not rite i have a tdi with a mechanical pump i fitted  not realy sure if it works proper though i have just posted a question about mechanical pumps on tdis ,
is yours a mechanical pump or elictronic?
cheers

Mine is the mechanical pump,  although it has some electrical connections on it which I am hoping to ignore.  Thanks for the advice, i hadn't thought about the heater plugs.
