Fuel Pump Control Unit: Description and Operation

SYSTEM DESCRIPTION 

This system controls the fuel pump operation. The amount of fuel flow delivered from the fuel pump is altered between two flow rates by the
FPCM operation. The FPCM determines the voltage supplied to the fuel pump (and therefore fuel flow) according to the following conditions.

COMPONENT DESCRIPTION 

The FPCM adjusts the voltage supplied to the fuel pump to control the amount of fuel flow. When the FPCM increases the voltage supplied to the
fuel pump, the fuel flow is increased. When the FPCM decreases the voltage, the fuel flow is decreased.
