Abstract
A fuel control system includes a pressure comparison module that generates a pressure control signal when a fuel supply pressure is greater than a predetermined pressure value, a temperature comparison module that generates a temperature control signal when a temperature of an engine is greater than a predetermined temperature value, and a pre-crank fuel module that selectively dispenses pre-crank fuel prior to cranking the engine based on the pressure control signal and the temperature control signal. A related fuel control method is also provided.
