Thanks for the replies guys, RAC man came out and managed to get the car to drive (not very willingly) but it would possibly appear that the half a jerry can of "fuel" I put in could have infact been water! And I then put another 5 litres of petrol in to the car...(which was petrol!)
He drained the fuel tank and lines and then we put 10 litres of petrol in again. We now seem to have another prob as the car now won't "spark" and the fuel lines don't prime and so no petrol getting through, so injectors not injecting.
Car is being towed to the garage this morning...(hopefully a simple/quick fix?!)
