Buy it up and have it towed home...

and if it's got dual tanks on it check the switch in the dash that allows either tank to be selected. I have forgotten how many Fords I have changed out the dash switch because they go bad.... check the switch connector too for corrosion/burned terminals...

The swith is a DPDT switch On-On style. One set of contacts switches the pumps in the tanks, the other set switches the sender wires for the correct pump/tank selected.
send1- - pump 1
gauge- -+12volts
send2- -pump 2

You can try manually jumping the switch connector with wire, the center switch terminals are dash gauge and pump power feed. Find which middle terminal has 12 volts with key on and jump it to an outside contact on the same side. Likewise with the other middle to see what the tank is reading. Listen at the filler neck to hear pump running when trying to start. No pump noise with battery voltage applied = bad electric pump in tank.

Another thought is that if he filled both tanks and flipped the switch maybe it has air trapped in the fuel system that has to be bled? Dunno if these need the diesel fuel system purged manually or if they do it OK by themselves...

Mileage a bit high but OK. I have seen these go 500K
