You appear to be losing the spark after the engine starts.

Did you ever get round to changing the dis pack.

Did you get a replacement for the genuine GM crank sensor that was faulty.

Yes mate, the faulty GM sensor has been replaced and the car now starts and drives fine but once it warms up it begins to missfire and then cuts out, when I replaced the sensor the first time the car would only start for a few minutes then cut out or would not start at all.

From your reply, it seems you have not tried another dis pack.

It is your choice but that's were I'd be going, if only to eliminate it.

No mate I havent replaced it, got so p***ed off with it that I sent it to a mechanic. Would the DIS pack cause it to missfire when warm but not when cold? I thought it was odd that it starts fine now when the engine is cold but will not start when it is warm.

Dis pack can deteriorate rapidly under load, especially, as you have already said the foam under the scuttle was damp, so must assume water has been dripping on dis pack.
I cannot say for sure that is your problem, but that's were I'd be going, if only to eliminate it.

Camshaft sensor replaced today and made no difference, told the mechanic what Kneepad said about the DIS pack and he agreed. Being ordered in the morning and fingers crossed it will cure the problem.

Defo looking like its the coilpack causing the problem, mechanic removed the old 1 on Wednesday and it is disintegrating badly in places and was damp, new 1 was ordered but did no arrive until today due to the weather so its going to be Monday before he gets it fitted, hopefully it sorts her out.

New DIS pack fitted today, car started fine but is still missfiring and then cutting out as before and logging the code for crank sensor as well, any ideas? Mechanic is going to check crank sensor to ECU wiring tomorrow, but other than there being a breakage he thinks it may be a fault in the ECU.

Sorry to hear you're still having problems with this.  :(
When you changed the crank sensor last time didn't you get a new wire/plug with it?

Do u mean the wire that runs from the crank sensor to the plug near the DIS pack?

Yes it came as part of the new sensor mate, its sealed onto the sensor with the oval type plug at the other end.
