摘要:
An engine control system includes a fuel system including a first fuel pump in fluid communication with a fuel tank and a second fuel pump in fluid communication with the first fuel pump. A pump control module selectively turns on the first fuel pump when a door opens before an engine is started, the engine is not cranking and a rail pressure of the first fuel pump is less than a predetermined rail pressure.
