Can you hear the fuel pump engage when you first turn the key forward? Do not attempt to turn on the truck but just place it in the on position you should be able to hear and feel the fuel pump for approximately 3 seconds. If not you have a fuel pump relay problem if not the pump itself.

does fuel pump run when you turn key to the run position...open gas cap stick in a funel put ear to funnel.. have some one turn key to run position......does check engine light come on when key in run position.......they have two very common problems....first the fuel pump relays and next very common problem is the ground for the ecm...main computer.....look at the battery then look at ground or negative wire you wiil see a smaller wire comming off the terminal. these will got to a bullet looking connector...cut out this connector and hook wires directly. even if not your problem it will be one day...write back if more needed
