its impossible to get the engine 180*out from the cam, because its 180* out every other rotation..
turn the engine another rotation and check the timing marks again 
True;
but pump to cam out by 180* is possible, due to pump to pump pulley assembly error is it not?
Not relevent in this case it would appear...
This is possible and it will run with the pump out 180 of the cam...it just doesn't run well.

yes, you can get the pump and cam out.. the pump sprocket and cam sprocket are the same size. so if you turn the cam 1 turn, the pump also goes the same 1 turn, not 2 turns like the engine..
every other stroke, the engine is 180* out from the cam and pump..
so, if your crank is 180* out from your cam and pump, all you need to do is rotate the engine one more turn.
all seems to be sorted now, popped in a 210mm sachs clutch i had lieing around along with the flywheel from my 2.0l gti engine sitting in the garage. took her out for a spin and seems i left 1st gear on the drive somewhere as its impossible to engage. new gear linkage kit in the post
