What are the reasons for the fuel pump not receiving electricity?
1 Answers
Possible causes include faults in the fuel injector input and output circuits, such as loose wiring or poor connectors; it may also be burned out due to voltage fluctuations from other parts of the vehicle, resulting in no electricity; or it could be due to its own issues: aging, internal wear, excessive heat from blockage, excessive gap, or poor conduction or burnout due to reaching the end of its lifespan. The function of the automotive fuel pump: The automotive fuel pump is responsible for drawing gasoline from the fuel tank and delivering it through the pipelines and fuel filter to the float chamber of the carburetor, enabling the car engine to start and power the vehicle. It is because of the fuel pump that the gasoline tank can be placed at the rear of the car, away from the engine, and below the engine. Types of fuel pumps: A fuel pump is a lightweight and compact pump, categorized into three main types: in-line, distributor, and unit pumps. The fuel pump requires a power source to operate, with its lower camshaft driven by the engine crankshaft gear. Movable molded parts: The fuel pump features a housing made of aluminum-containing material and a movable molded part installed within the housing. This movable part is at least partially made of a sinterable, iron-based alloy material containing austenite, and the sinterable material of the molded part has a thermal expansion coefficient that is at least 60 percent of that of the housing.
