Fuel Injector: Description and Operation
When the Automatic Shut Down (ASD) relay contacts close, they connect circuits A14 and A142. Circuit A142 supplies voltage to the fuel injectors.
Each injector has a separate ground circuit controlled by the Powertrain Control Module (PCM).
Circuit K11 provides ground for injector number one. The K11 circuit connects to cavity 16 of the PCM.
Circuit K12 provides ground for injector number two. The K12 circuit connects to cavity 15 of the PCM.
Circuit K1 3 provides ground for injector number three. The K13 circuit connects to cavity 14 of the PCM
Circuit K14 provides ground for injector number four. The K14 circuit connects to cavity 13 of the PCM.
Circuit K15 provides ground for injector number five. The K15 circuit connects to cavity 38 of the PCM.
Circuit K16 provides ground for injector number six. The K16 circuit connects to cavity 58 of the PCM.
