1. Fuel Starvation: When the vehicle runs out of fuel, the fuel supply to the injectors is cut off. This means that there is no fuel available for the injectors to spray into the engine.
2. Loss of Combustion: Without fuel, the engine will not be able to generate combustion, and the vehicle will eventually stall.
3. No Power to Injectors: Once the engine stalls, the electrical power to the fuel injectors is also turned off. This is done to prevent the injectors from continuing to spray fuel into the engine, which could lead to flooding and engine damage.
Therefore, since the fuel injectors stop receiving power when the engine stalls, they do not have the opportunity to overheat and burn. Fuel injectors are designed to operate within specific temperature ranges and are protected from overheating by the vehicle's cooling system and fuel pressure regulation mechanisms.
However, it's important to note that repeatedly running a fuel-injected vehicle out of gas can lead to other problems, such as damage to the fuel pump and fuel filter due to excessive strain and overheating. These issues can potentially cause injector failure or reduced performance, but not directly from burning out due to lack of fuel.
