RAM 1500 Truck 4WD V8-5.7L VIN D (2005)
Battery voltage (12 volts +) is supplied to the injectors through the ASD relay. The ASD relay will shut-down the 12 volt power source to the fuel
injectors if the PCM senses the ignition is on, but the engine is not running. This occurs after the engine has not been running for approximately 1.8
seconds.
The PCM determines injector on-time (pulse width) based on various inputs.
