Hi everyone, I have a 58 reg zafira 1.9 diesel. last week my alternator pulley broke and chewed up the fanbelt. I have had a new alternator, timing belt and fanbelt fitted but ever since my car has been very hard to start. So I changed the glow plugs, serviced the vehicle and replaced the starter motor. Now the spanner light is always on and still the zafira is hard to start and when it does start it is juddering and the whole dashboard vibrates when I press the accelerator. I am at my wits end and my mechanic is now saying that it may be the manifold air pressure sensor. When attached to the computer there are no fault codes. Can anyone help me out please.

There was no debris in the engine but I changed the timing belt just to be on the safe side. I relaced the air pressure sensor that sits on the manifold but still I have the same problem. The pedal trick gives me code ECN 034028

when your fan belt broke did it end up in the timing belt/pulley area?If it did you may have bent valves resulting in low compressions,other than that it is difficult to determine your problem if no fault codes are showing.
