of fuel consumed, the fuel pump control module (FPCM) determines
whether to activate the low pressure fuel pump.
After activating the low pressure fuel pump, the FPS
continues to provide the fuel pressure information to the FPCM and the
FPCM keeps controlling the fuel flow rate using the feedback information
from the FPS.
