GENERAL DESCRIPTION
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.
Scheme 1
A vacuum valve and pressure valve are built into the fuel filler cap which adjusts the fuel pressure in the fuel tank to prevent fuel tank damage.
