There is a 6 wire connector on the injection pump disconnect it and see if it runs during the failed state.Also check the ground on the pump and clean as needed.If it runs with the 6 wire connector disconnected you will have to replace the injection pump.Is the check engine light on?If it is go to Autozone and get me the code numbers.

try smelling your fuel dose it smell like gas or diesel fuel?
Expert:  Davo replied 11 years ago.
 Well I will assume you know how to check for water and air leaks.To continue a diagnosis you need scan tool unless you wish to throw parts at it. How do you know the lift pump is working properly? I think you are pulling in air somewhere nothing personal.
