1. Fuel Tank Vent: Check the fuel tank vent for blockages or restrictions. A clogged vent can cause a vacuum to form in the tank, making it difficult for fuel to flow in.
2. Faulty Fuel Filler Neck: The fuel filler neck may be deformed or damaged, preventing the fuel pump nozzle from inserting properly and creating a seal.
3. Faulty Fuel Filler Cap: A loose or damaged fuel filler cap can allow air to enter the fuel system, causing the pump to shut off prematurely.
4. EVAP System: The EVAP (Evaporative Emission Control) system may be faulty, causing the fuel tank to pressurize and preventing fuel from flowing in smoothly.
5. Fuel Pump Module: The fuel pump module, located inside the fuel tank, may be defective or have a clogged fuel filter, restricting fuel flow.
6. Check Valve: There might be a faulty check valve in the fuel filler neck or the fuel line. This valve is designed to prevent fuel from flowing back out of the tank, and if it's malfunctioning, it can cause the pump to shut off.
Solution:
Identifying the exact cause of the problem is crucial for a proper solution. It is recommended to visit a mechanic for a professional diagnosis and repair to avoid further complications and ensure the safety and efficiency of your vehicle's fuel system.
