Yep the chip is still there mate.

Some1 on Migweb suggested possible coolant temp sensor.

Have you changed the plugs as was suggested earlier?
Is, or was there any oil in the plug wells?
Is the foam under the scuttle above the dis pack wet/damp?

My main reason for asking this was to get an answer to the next question.

Right had a mechanic up to take a look at her this evening and it is def electrical and not fuel related. Fuel system is functioning fine but when he removed a plug lead and put a screwdriver into it to see if there was sufficient spark. Managed to get the engine to fire and it sparks fine for a few mins then the spark stops and engine dies. Thinking maybe coil pack?

Ok that's where we are heading but you are not answering the questions.
If there was oil/water in the plug wells you may need new leads.
If you have water dripping from the scuttle then will almost certainly be dis pack.

Foam above the DIS pack seems to be damp, plug leads on drivers side were very hard to remove and plugs seem ok.

The it looks like we are back to reply no. 1 from
'Diamond Black Geezer' Dis Pack.

Have a good look around the dispack and see if there is any signs of corrosion, splitting, delamination.

Expensive item to replace, I would also replace the leads. Try in the wanted section and see if you can get a known good dis pack and leads from someone who is breaking a car.

Technically you only remove 4 Torx headed M6 bolts. In practice .....  ::) you'll also need a box of plasters for afterwards.  ;D ;D ;D Remove the scuttle and you can feel for the Torx bolts - I used an ordinary 8 mm 1/4" drive socket. The first time you see it is when the last bolt has been removed.  :-? :-? Just awkward  ;D ;D

Ok 3 weeks later and the car is still not working. It now starts, turned out the new Crank sensor was faulty, got a new 1 and it starts ok. But it has now got a missfire when the engine gets up to temp and this then causes it to cut out and it then wont start for about half an hour.

I have left it with a mechanic who says that when this happens it is logging the fault code for the crank sensor again and 1 for a signal to the ECU, he thinks possible camshaft sensor or maybe coolant temp sensor, does this sound right to anyone?

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.
