Thanks heaps chris. I replaced the TPS and the fault code has dissapeared. (I didn't go to much effort, a mate around the corner had a spare!).

This is all good and well but the real reason the car wouldn't go was a hmmm lack of petrol.

Somehow in about the last 4 months I have gone through 10 litres of fuel with barely even moving the car. Does the fuel tank hold a small amount of petrol below the outlet? That's the only way I can explain the fact that I put 10 litres in and had already run out.

Sorry to waste your time!
