1 Answers
When the fuel pump fuse is not blown but there's no power, check whether the wiring plug is loose or if there is water ingress causing a short circuit. Additional information: 1. Fuel Pump: As the most fundamental component in the engine fuel supply system, the fuel pump is responsible for drawing fuel from the fuel tank during engine operation and delivering it continuously to the engine at a certain pressure through the fuel supply line. The high-pressure fuel pump then performs secondary pressurization, supplying a measured amount of fuel to each cylinder according to the engine's firing order. 2. Fuse: In the automotive electrical system, many electrical devices are connected by wires of different colors, among which the most important should be the fuse. The term 'fuse' is a customary name, referred to as a 'fusible link' in national standards. The function of a fuse is to protect the circuit (wiring) and electrical devices.
