Tank Selector Valve issues

Having issues with my tank selector valve, right now its set to the front tank and runs fine, but the dash mounted switch doesnt seem to have any power going to it.

At first we thought the frame mounted valve switch was the issue so we replaced it but its still not working.

The fusible links in the inner fender all have continuity and the fuse labeled “Electric Fuel Control” works fine.

We tried bypassing it and using an unused fuse slot to give what we thought was the power cable on the switch power, but that just activated the high pressure fuel pump at the front.

Currently at a loss for whats wrong or what to do so any help and/or ideas would be
appreciated.

does it have the plastic diverter manifold style? probably the valve is dead.

Yes but the issue is we were checking the wires thag plug into it and there was only a signal on one of the 5 ports and all the rest were dead even when the switch was flipped.
 
the last thing i posted has a pigtail and new switch.
