No.
No, two separate circuits.
The wires to the fuel pump are not connected correctly or are disconnected.
THE FUEL PUMP FLOAT HAS GONE BAD OR THE GAUGE NEEDS TO BE CHECKED
A plugged fuel filter can cause the pump to fail prematurely due to it having to work harder to pump the fuel through.
The gauge could be bad, the fuel gauge sending unit in the gas tank as part fo the fuel pump could be bad you could have a bad ground wire you could have a broken wire in the harness runnign from the fuel tank to the gauge.
Several things can cause your fuel gauge not to work. The most common cause is a bad ground wire. A malfunctioning float in the fuel tank can also cause the problem.
More than likely the float is bad on the fuel pump, so i would recommend that you change the fuel pump.
The sending unit is located on the fuel pump which is located inside the gas tank.
Several things can cause the fuel gauge to stop working. 1.The sending unit in the fuel tank may be malfunctioning or broken. 2.There may be a broken, disconnected, or grounded wire going to the fuel pump/sending unit. 3. There may be a disconnected wire at the gauge cluster, or the gauge cluster itself may be malfunctioning.
if you put gas in the tank the gauge don't work what is the problem Probably the sending unit in fuel tank is corroded. Either replace unit wit a new fuel pump or try pulling pump out and cleaning crud from float unit and sending unit and the contacts. Fuel pump is in fuel tank
constantly running your car with low fuel will burn out your fuel pump
Bad fuse - I believe it is fuse # 17 - 15 amp for the fuel gauge on your 1994 Explorer bad sending unit - it's combined with your fuel pump inside the fuel tank bad wiring connection possibly the gauge itself
