Fuel Pump Issue

[Gravy]

First off, this seems to be a ground issue, but than again i'm not 100% sure how, or why. Keep in mind, we tested everything short of using a volt meter testing everything.

(91 Dodge stealth RT/TT fuel pump rewire, remote battery in the trunk with dedicated ground wire going straight to the fuel pump bracket bolted to a clear rust free spot on the top of the bracket though one of the studs)

But it may have started last fall, my fuel pump was cutting in and out and when i started looking, i was getting a knock count of about 30 at idle, and around 70 just cruising. Pulled the knock sensor now i'm getting the right knock count, but my fuel pump doesn't work. I have a rewire done but tried running it with, and without the rewire being on there. Same problem both times. Now, i cleaned a ground, or three on the fuel pump mounting plate, and can get the fuel pump to run by using alligator clips providing a ground to the plate. However, when the plate is bolted to the tank all the way, it doesn't run even with the alligator clips on the tank, studds, bolt, or factory ground wire going to the mounting bracket.

As of right now, with three of the bolts off the fuel pump mounting plate i can get it to run, if i put one on and the MOMENT it makes contact with the plate, i loose ground. I back it off(no pressure, just touching mind you) so that it's free hanging on the top of the stud, it runs. Same with the bolt on the other side. Now, i know this is kinda gheto, but it's late at night and febo and i tried our damndest with neither of us having a volt meter. That being said, electrical tape applied under the bolts preventing them from touching the mounting plate(but still making contact to the studd and fully torqued down) we can get it to start intermitinly, but unsure as to why.

Ground is good from the pump to the fuel pump mounting bracket, and when the pump is hanging over the tank not touching, it runs. But if we put it down and put two bolts holding it down, it works, third one down, it works. Forth one down, no ground even after re-torqing the other bolts down. It is bolt specific as well, bolts 2 and 5 can not be used as the two holding it down, the others can be used in any order/combination and it runs.

If anything isn't clear ask questions, or you have any idea why this might be happening, let me know. I'm open to options, and this has by far been the weirdest thing i've run into with a DSM, or it's retarted cousin. Would love to get it working fully bolted down and ready to run this summer to sell.
