Alright I need some help, I got a 94 f250 with dual tanks. I'm getting no power to either fuel pump and the fuel gauge goes all the way past full and they barely have any gas in them. The truck has sat for 2 years but I replaced the back tank fuel pump before it sat and it had barely 10 miles on it. The fuses look fine, I swapped the relay for the horn and the fuel pump and nothing, but the horn doesn't work either. I had someone turn the key and I put my ear near the tanks and heard nothing. Im guessing it might be the tank switch on the dash but not sure how to check if it's any good.
Also its 5.8L gas if that helps
Ok so I replaced the tank selector switch and the relay nothing. There's a four prong connector going to the tank with a black, black with white line, orange, and yellow with green line wires. Using a meter and having the key turned on I was getting 0, then 8, and 6 volts.

Passenger side under the kick panel to the right of the glove compartment there's a fuel cutoff switch, check to see if it's tripped.

Its probably the fuel pump/Crossover unit itself. Which is fucking expensive.
I have a 95 F150 with dual tanks and only the rear one works, pretty much narrowed it down to that.
