Fuse 27 relocation inefective.

[DCSVT1]

I turned the key on, went under and got power from 5 & 1, but it only lasted for a minute or so. (Key on, climb under truck) checked all the pins. 5 a 1 had power. But by the time I checked others and back to 5&1, neither had power. ??

Surprised 8 doesn’t have power if 5 does, also why 1 looses power. Could the relay be going bad?

This is the plug going to the new fuel pump driver module. Swaped it out before the trek home and it died about 20 min shy of hhoe when i stopped for gas. Checking everything before dropping the tank again.
UPDATE/1-17/ Found the original FPCM and swapped it back in and no change, still cranks but no go. BUT i did notice that the fuel level was @ zero. This died after i got gas so i know there's atleast a half-ish tank, not zero. That makes me think it's either a fuse or the plug at the pump. Will have to tripple check the fuses again.

Running tests front to back; fuses and relays under the hood all check out. Voltage to the FPCM gives odd signals. 1 hot wire (11.5) and nothing else. Ground gives me enough volts to trigger the "." On the meter. Flash back to a year or 2 ago, the harness fell onto the header and causied a bunch of weird issues before it died. I checked that today and sure enough it was real close and a little crispy. Will have to pull the wheel and Liner for a better look in the near future. Garage sealed up due to fire. No access until fire inspectors, and everybody does their inspections. Noting but bad luck recently...on the plus side it'll give me time to hunt down a new engine harness.
