Fuel Pump Relay

In order to control the 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 it 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.
