So I solved the problem, it was really simple. I grounded that set of grounds to the coil bracket on the valve cover. Apparently, this is a bad idea. I moved the ground to the alternator bracket and my gauge started working and the pump kicks on. I still sdont know why my test light was showing voltage....

Now, my truck would crank over BEFORE i would ground the fuel pump relay. Now it won't crank. I had an issue where the PRNDL switch wasn't allowing it to crank. I bought a new one and it fixed that problem. Now since I fixed the fuel pump.... it wont crank again...
