Fuel Pump Relay: Description and Operation

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

When it is turned to "START" position, the Power Train Control Module (PCM) receives the reference pulse from the Ignition Control Module and it operates the relay, again causing the Fuel Pump to feed fuel.
