Guys (& Mindy),
I can't thank you all enough for your help, I literally couldn't begin to say how blown away with the support you've all given me over this.
OK, spurred on with your encouragement...
I thought the starter was ok as it turns over ok (for now!) but will check connections now the car is back in the garage and access cover can be left off.
So jobs to do - in this order:
1) Plugs out after turning over and check for petrol smell.
2) CAM sensor getting a clean.
3) CRANK sensor getting replaced.
4) Listen for a 2 sec whirring noise on turning ignition on.
Now the scary bit - Thankfully I don't smoke - fuel pipes...which pipe is the outlet side of the fuel pump? Orange / Green - i'm guessing orange?
Russel - as said on email - can't thank you enough for the chat the other night and CPS.
Look forward to feeding you bacon butties (no butter) and coffee (2 sugars) sometime soon.
