Abstract
A system and methods are provided to deactivate a cam driven fuel pump. The system comprises a direct fuel injection system; a port fuel injection system; a pump for the direct injection system driven by a cam, wherein the pump can be activated and deactivated as a function of the activation of the direct injection system. Deactivating a pump when no fuel is pumped through it minimizes wear on pump components and increases efficiency.
