    What belt should i use to delete the ps pump

    I have no clue why i cant steer.. I thought maybe the slide collor was trashed, but it looks good.. I think maybe its just the over all weight and the 12 inch wide wheels

    Scan tool?

    Not to sound completely crazy, but i feel the edge insite is a good tool itself.. You can log and read codes and it works on different makes and models.. You can't program with it or anything but still you can do a decent amount.. I have a uscan from the local parts store and it works.. But uou...

    Huge Fuel Leak

    I just replaced one on an lbz, there are some people out there that have a few tricks however it will be faster if you remove the brackets off the front of the motor and slide them forward.. Unbolt the cp3 and take of the coolant cross over.. Then you can pull it right out..

    Allison 6sp: No forward or reverse. No codes.

    This my be a stupid question.. But is the truck 4wd and if so did you try driving in 4wd high? Or is the drive shaft not spinning at all?
