WARNING: This page is about a different car, the 2010 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

The Fuel pump control module (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.
