Starting problems.

[Hdiestate]

Right guys the last couple if weeks ive been having problems with starting the bus. Its mostly when hot like if i drive for 10mins pop in a shop it will take 4-5 cranks to get going. I thought it was the key but ive changed it for my spare still the same. Ive had a quick serch around and it sounds like a low fuel presure problem or fuel related. Theres no lights on or change in performance nor mpg.

I can plug it in to a snap on ethos on tuesday but till then any1 got any thourghts on what it could be. Cheers
