Fuel Pump Fuse
The fuel pump fuse is located in the power distribution box as well. It is a 20-amp fuse that is designed to protect the fuel pump from electrical surges or short circuits. If the fuel pump fuse is blown, the fuel pump will not work, and the engine will not start.
Fuel Pump
The fuel pump is located in the gas tank. It is responsible for delivering fuel to the engine. The fuel pump has two wires that connect to it. One wire provides power to the fuel pump, while the other wire is a ground wire. If either of these wires is damaged or disconnected, the fuel pump will not work.
