The ground is on top of the radiator support which can become loose or broken.

I have already checked the inertia switch, and it was not triggered, although I reset it any way just to make sure. And it was located on the passenger side on the kick panel. My truck seems to be the complete opposite of what its supposed to be I swear. Any other suggestions? I am at a complete loss of ideas right now. Thanks

Is the vehicle definately not getting fuel ? and there is definately a hot feed to pump ..if yes .. check the ground(orange)wire near the top of radiator support or ground the pump(orange wire) to another ground point near the pump on the chassis somewhere .. or you could run a hot and ground direct from battery through a switch to the pump so you can check it is working correctly ?? making sure you remove the origanal hot and ground wires from pump ? let me know
