* Empty tank: The most obvious reason for a lack of fuel.
* Fuel pump failure: The pump may be malfunctioning or have failed.
* Clogged fuel filter: A dirty filter restricts fuel flow.
* Faulty fuel injectors: The injectors may be clogged or not working properly.
* Other electrical issues: Problems with the fuel system's wiring or computer controls.
If you're experiencing fuel problems, take your car to a mechanic for diagnosis and repair. Trying to "reset" something that doesn't exist won't solve the underlying issue.
