Hello All, With the hot start problem I keep having I have almost given up on the problem. As I have tried everything bar change the fuel pump incase the valve has gone this is what I did for now. I have a switch now on the console with a light on it and when the car won't start from hot I can press the switch it activates the cold start valve and then I switch it off quick so I keep the engine running,works fine once you time it right. It's just a way round it by not going to the engine and swaping the plugs around. Paul Heymeson.Vin 741.
