Firstly it wont be a pump timing error as the pumps are not timed at all on the Hdi. Its all done by ecu triggering the injectors in the correct order.

My guess is your cam to crank timing setting is out. Take the engine back to Tdc and try and put your timing pins in the cam sprocket ( at 7 oclock roughly) and in the crank hole behind the starter. Both sbould go in easyilly.

I think you may be a tooth out.

Is the cam pulley the type with the three bolts or the single bolt in the middle ? If its the type with the three bolts did you make sure they were loose when tensioning the belt ? If you don't it can pull the pulley round when tension is applied to the belt & knock it out slightly.

Before buying an injector swap it with the one next to it and see if the fault moves.. if not then the fault is electrical.

Dont worry these systems are not that sensitive you can move them around with no effect..

All 8v 2.0 90bhp and 110bhp ones are the same yes..

yea just tried that and still the same...the end off the injector is like its been polished and no visible holes...like metal fillings from the broke pump have welded it closed...luckly my friend who has the engine i aquired the pump off has injectors....but do they need codeing?
thanks paul :)
