Did you try as Roy suggested & did you check fuel pipe as suggested?
You could at least say whether you have tried their suggestions or not after people have tried helping you. It really annoys me when I try helping someone & they seem to ignore every suggestion that I make. I expect that saying you couldn't fault anything else, means that you have checked their suggestions, but I think it needs to be made clear.
Sorry for moaning at you , but it's this sort of thing that stops people bothering to reply to posts.
