Abstract
A control system includes a fuel pump control module and a diagnostic module. The fuel pump control module controls a fuel pump to provide fuel to a fuel rail. The diagnostic module controls the fuel pump control module to provide a predetermined amount of fuel to the fuel rail, determines an estimated pressure increase within the fuel rail based on the predetermined amount of fuel, and compares an actual pressure increase within the fuel rail to the estimated pressure increase. The fuel pump control module selectively controls the fuel pump based on the comparison.
