The Fuel Pump Test Connection in the wire bundle near the ECM cannot power the fuel pumps when the ignition is ON.
The fuel pump test connection is very useful when 12 Vdc is applied with an ammeter. A running fuel pump will draw about (I don't remember the exact number) 4 amps. If the ammeter reading is > 8 amps, then two pumps are running in test mode.
