dead 166

[Catchpole]

Well, not quite dead but certainly not v well. Would be grateful if anyone has any bright ideas as my mechanic has run out of them. 166 2.5 with 80,000 miles, developed an occasional miss on long trip one weekend. Got worse & 2 days later it cut out completely. Would start after a while and run for a few minutes before cutting out again. Home courtresy of the RAC.... Garage says that computer shows no faults now that they've changed a flywheel sensor, but there is no spark at the plug when the starter motor is spinning. Fuel pump is apparently fine. Help!

It seems that there's nothing going to either the injectors OR the plugs. They are currently investigating the immobiliser but no joy yet......
