To test the electric fuel pump on a 1997 Chevy Lumina, start by checking the fuel pump fuse and relay to ensure they are functioning properly. Next, locate the fuel pump test connector in the fuse box and use a jumper wire to connect the terminals, which should activate the pump; listen for a humming sound. Additionally, you can check the fuel pressure at the fuel rail using a fuel pressure gauge to see if it meets the manufacturer's specifications. If the pump does not activate or the pressure is low, it may need to be replaced.
