Powertrain Control Module: Description and Operation
Fuel Charging and Controls

The Powertrain Control Module (PCM) controls the fuel injection system. Injector pulse-width is varied to control the amount of fuel flow through the
injectors and into the engine. Varying fuel pump output controls fuel pressure. The PCM commands the fuel pump driver module, which directly
controls the fuel pump.
