Section 03-04B: Fuel Charging and Controls, 5.0L and 5.8L Engines | 1996 Vehicles Equipped with 5.0L and 5.8L SFI V-8 Engines Workshop Manual |
The fuel charging wiring (9D930) connects the engine wire harness to each fuel injector (9F593) and other electronic engine controls such as throttle position sensor (TP sensor) (9B989) and idle air control valve (IAC valve) (9F715). The fuel charging wiring receives fuel injector actuation signals from the powertrain control module (PCM) (12A650) and transfers the signals to the fuel injectors. The signals from the powertrain control module determine the fuel injection sequence and duration each fuel injector will stay open to allow fuel into the combustion chambers.
