The Electronic Gas Injection (EGI) system, consists of the fuel pump, pressure regulator, injectors, a pulsation damper, fuel lines and hoses, various engine sensors, and an Electronic Control Unit (ECU).

The ECU monitors the sensors and then determines the amount of time the injectors are opened.

The injectors are directly supplied with battery voltage through the main relay. The ECU grounds them to complete the connection.
