Who is correct about immobilizer systems disabling fuel injectors?

The assertion that is correct regarding immobilizer systems disabling fuel injectors highlights an important function of these systems in modern vehicles. An immobilizer is a security feature designed to prevent unauthorized engine start-up. When a vehicle's immobilizer is activated, it often disables critical components of the engine's operation, including the fuel injectors. This means that without the proper key or coded signal, the engine management system will prevent the fuel injectors from delivering fuel to the engine, effectively immobilizing the vehicle and making it inoperable.

This process helps to deter theft by ensuring that even if someone tries to bypass the ignition switch or hotwire the car, the engine will not start without the correct authentication from the key or fob. In contrast, if the other options do not fully address this aspect of how immobilizers function concerning fuel injectors—either by presenting inaccuracies or misunderstanding the role of the immobilizer—then they would not be deemed correct in this context.
