the bit where you say about the idling the car has had a mind of its own twice in the last week it started revving from normal idle and jumped up to 2000rpm then a couple of days ago before i went to take it to the rollers i had just put fuel in her then when i started it again it started idling at 3000 rpm switched her of and it was back to normal. ill get the fuel pump checked tonight but i do have a loom already run in for it, it was a new pump last year and i also have a new filter sitting around. what should the pump voltage be at on idle and then under load?

thanks for your help mate
