Does anyone know if it is conceivably possible to get the timing wrong on an injector pump of a 200TDi with the pin in?
I removed the timing belt, sent the pump away to be tested and re-assembled with a new belt, but the vehicle won't start. Lots of head scratching later and I'm convinced the pump is pumping (fuel comes out the injectors etc etc) and the engine runs on quick start, so I know the cam / crank timing is right (it definitely never moved while the belt was off anyway). It is as if the pump is 180 degress out or something - everything appears correct, yet it won't start or even try - it's DEAD (I've even tried a very long tow start). Timing marks are all 100% correct - pin in flywheel, pin in injector pump, cam 'dot' spot on arrow.
When the pump was away, could they have refitted the metal plate on the front of the shaft that takes the locking pin incorrectly? Would they have taken it off to fit the pump to the jig? Could they have done anything else to mess the timing? Does the pump have 2 cycles, since it's a 4 stroke and could therefore be 1 whole turn out? (I've tried that and it never worked, so I assume not.) Any ideas fellas? I'm sure it's not something else more obvious - I've been through this for 2 weeks now and I've bled and bled and checked everything else possible.
