My brothers C14NZ corsa is running on 3 cylinders and we were wondering he anyone could shed some light onto what is wrong with it. I've connected my laptop up to it and there aren't any fault codes. There is no change in its running no matter what the revs are. Took off injector plug 3 so we know what cylinder isn't firing.
Any help massively appreciated.

The lead works fine, took it off and put onto another spark plug and earthed that on the head and it sparks fine.

Not 100% where it is but should be near the cam normally on the end. May not always put a fault up though

Easy to tell if its broken? Or is it a case of replacing it for a new one?

Was on MSN to Keith and told him its losing a bit of water. Think thats why he said that. We haven't run it with no spark plug in no.3 but tested no3 lead with another spark plug we had spare.

so you have changed the spark plugs, tried new leads and new coil pack? i would get a compression test done on cylinder 3 if i was you and also get a tester to check if the head gasket has gone, sounds like the head needs to come off thow.
