To test the fuel pump on a 1996 Subaru Outback, first, ensure the vehicle is off and disconnect the fuel pump relay. Then, use a multimeter to check for power at the fuel pump connector while turning the ignition key to the "ON" position (do not start the engine). If there is power and the pump does not run, you may need to replace it. Additionally, you can listen for the pump's sound when the ignition is turned on, as it should briefly activate for a few seconds.
