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.
bad ground or float stuck 2 possibilities i can think of
No , the 2.9 liter V6 engine in a 4X4 , 1990 Ford Bronco II is fuel injected
The Bronco 2 was sold between 1984 and 1990. The Ford Bronco 2 was a compact SUV. It was smaller than a full-sized Bronco. It was succeeded by Ford Explorer.
In the tank
No
If it is the same as the ( 1996 ) Ford Bronco : ( Relay # 2 is the fuel pump relay )
My husband just replaced my fuel pump yesterday...86 ford bronco II with 2.9 ltr engine...it is located inside the fuel tank, cost about $60 at Napa Autoparts...note: my bronco has 4 wheel drive option. 6-25-06 Yes it is electric and is mounted externally on the fuel tank. Actually there are 2- one in the fuel tank with the gauge and pick up and another on the frame rail drivers side apx. front edge of drivers door.
Clogged fuel filter, defective fuel pump are 2 possibilities.
No, just one.
Fuel gauge problems are usually the fault of the fuel gauge sending unit in the fuel tank, just saying.
The fuel presure for the 2.9 liter V6 in a Ford RANGER is ( 30 to 40 PSI ) I assume your Ford Bronco II , 2.9 would be the same * with fuel injection
