I am getting no power to my fuel pump, fuel pump relay, or my enertia switch no fuses are blown and I have checked over all the wires but there is a wire with a built in fuse going to the selinoid do you think that fuse could be blown cause the truck to not get any power to any of those elements or could there be something else causing it to do that?

You may have already checked this, but when this happened to me, it turned out to be the fuel tank selector switch. $7 a local junk yard and two screws later I was back on the road. Afterward I talked to the guy who sold me the truck and he said he had to replace the same switch twice before. I now carry and extra switch for emergencies
