Fuel pump: The fuel pump may be malfunctioning, causing it to deliver insufficient fuel to the engine. This can be due to a worn-out pump, a faulty fuel pressure regulator, or a clogged fuel filter.
Fuel lines: The fuel lines may be kinked or clogged, restricting the flow of fuel. This can be due to age, damage, or the accumulation of dirt and debris.
Fuel tank: The fuel tank may be damaged, causing it to lose pressure and allow air to enter the fuel system. This can be due to rust, cracks, or a damaged fuel cap.
Fuel injector: The fuel injectors may be clogged or malfunctioning, preventing them from delivering the correct amount of fuel to the engine. This can be due to age, wear, or contamination of the fuel.
Evaporative emissions system (EVAP): The EVAP system may be malfunctioning, causing fuel vapors to escape from the fuel system and affecting the fuel level sensor's accuracy.
Fuel level sensor: The fuel level sensor may be faulty or damaged, providing an incorrect reading of the fuel level in the tank.
To diagnose the exact cause of the problem, it is recommended to consult with a qualified mechanic.
