* Fuel pump failure: The fuel pump is responsible for delivering fuel from the gas tank to the engine. If the fuel pump fails, the engine will not receive any fuel and will not be able to start.
* Fuel filter blockage: The fuel filter is responsible for removing impurities from the fuel before it reaches the engine. If the fuel filter becomes blocked, the engine will not receive enough fuel and will not be able to start.
* Fuel tank sending unit failure: The fuel tank sending unit is responsible for sending a signal to the fuel gauge indicating the amount of fuel in the tank. If the fuel tank sending unit fails, the fuel gauge will not work properly.
* Electrical issues: Electrical problems, such as a faulty fuel gauge sensor or a blown fuse, can also cause the fuel gauge to stop working and the fuel pump to lose power.
To diagnose the exact cause of the problem, it is recommended to take the vehicle to a qualified mechanic. The mechanic will be able to inspect the vehicle and determine the source of the problem.
