- The fuel tank vent allows air to enter the tank as fuel is pumped in, preventing a vacuum from forming. If this vent is clogged, it can cause the pump to shut off prematurely.
2. Faulty Fuel System Sensor:
- Various sensors monitor the fuel system, including the fuel level sensor, pressure sensor, and temperature sensor. If any of these sensors are malfunctioning, it can cause the pump to shut off.
3. Kinked or Blocked Fuel Line:
- If the fuel line, which carries fuel from the tank to the engine, becomes kinked or blocked, it can restrict fuel flow and cause the pump to shut off.
4. Faulty Fuel Pump:
- The fuel pump creates the pressure necessary to move the fuel through the lines and into the engine. If the fuel pump is malfunctioning, it can cause the pump to shut off intermittently.
5. Charcoal Canister:
- The charcoal canister is part of the vehicle's emission control system. If it is malfunctioning or blocked, it can cause pressure imbalances in the fuel system and lead to the pump shutting off.
6. Computer Issue:
- In some cases, a software issue with the vehicle's computer can cause the fuel pump to shut off. This is typically rare but can't be ruled out.
If the issue persists, it's best to have a professional mechanic inspect the vehicle's fuel system to accurately identify and fix the problem.
