If you give it gas dose it try to move at all?

yes it does sometimes aand at other times it just sits and surges as I think your thinking , hunting for gas

Dose everything spin freely when the truck isn't running?

mostly one of the rear wheels is a bit notchy, I think that might be down to me putting in a shim too many when I redone the rear diff but was planning to take that out tomorow

That just might be your culprit.

hey guys quick update pulseing sorted,took out the extra shim and the clutch was also shot so changed it as well and now it goes as it should, fast lol, just need to dial it in now any tips for that?

thanks again for all the help
