Abstract
A fuel system includes a motor-driven pump which pressurizes a source of fuel to a predetermined pressure level and delivers the pressurized fuel to an engine-driven pump which, in turn, communicates with high-pressure fuel injectors for supplying high-pressure fuel into respective cylinders of an engine during normal engine operation. A low-pressure fuel injector is provided which is connected to the discharge side of the motor-driven pump for supplying low-pressure fuel into an engine intake manifold near its entrance only during the engine is being cranked.
