Abstract
A diagnostic system is provided for aiding a technician or engineer in verifying that a fuel injector in a fuel injected engine is operating properly. The diagnostic system comprises a controller operatively coupled to an actuator for the fuel injector and to a fuel pressure sensor. The controller is configured such that, during a fuel injector test, the controller outputs a signal to the fuel pump so that pressurized fuel is supplied to the fuel injector. After the pressurized fuel is supplied to the fuel injector, the controller outputs a signal to the actuator to operate the fuel injector for a predetermined amount of time. The controller is also configured such that after the predetermined amount of time the fuel pump is turned off.
