The ECM provides ground to one side of coil of fuel pump relay to control the fuel pump relay. The other side of fuel pump relay coil is connected to main relay, which activates when the ignition switch is ON. The ECM monitors the control circuit of the fuel pump relay between the ECM and the fuel pump relay. When the ignition switch is turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump.
