I have a problem with the truck as it was working fine I went in the house for 1-1/2 hours then went out and tried to start it to go out. It coughed and sputtered then would only go through the motions of starting but would not start. Fuel is not getting to th intake manifold. What could it be? (A clog, fue sending unit, when we put fuel in the intake it wants to start but then burns up whatis there then stops again. Fuel pump is fine.

Fuel pump is fin as in you have 60 psi of pressure. The fuel system on this truck the pump wil run and pump fuel but has to have 60 psi because it runs on popit valves under the plantum and wil not open them with less then 60 psi. If you do have the right fuel pressure. Then the fuel injection controller is under the plantum kind of expensive but you have to know it is a fuel prob for sure good luck billymac
