I think 2.0 and 2.2 will start with either (cam or crank) sensor at fault but not both.

good point, run like a sack of spuds but will start.

Does the engine crank, or just nothing happens on the turn of they?

Different to a V6, will start without the crank sensor, but not if the cam sensor is at fault.

If it's a fault that has been introduced since the work was done then there won't be a stored code to read as it's never started IMHO.

i know you said the timing was spot on, you have a spark but do you have compression?? mixed cams up? 180 out on one cam?
