Abstract
A fuel control system for an internal combustion engine includes a fuel starvation detection module and a fuel pump protection module. The fuel starvation detection module detects when a fuel pump is delivering less than a predetermined amount of fuel based on a fuel level in a fuel tank, a fuel pressure in the fuel pump, and an air/fuel (A/F) ratio of the engine. The fuel pump protection module decreases an amount of fuel supplied to the engine during a period after detecting that the fuel pump is delivering less than the predetermined amount of fuel.
