In order to control the Fuel Pump Relay (FPS) operation, the FPS relay is provided. When the starter switch is turned to "ON" position, the FPS relay operates the FPS for 2 seconds.

When the key is turned to "START" position, the Engine Control Module receives the reference pulse from the Ignition Control Module and it operates the relay, again causing the FPS to feed fuel.
