Main Relay (Computer/Fuel System): Description and Operation

MAIN RELAY

The Engine Control Module (ECM) activates the main relay (2/32) when the ignition is switched on. At the same time the Fuel Pump Relay (2/23) is
activated for one second to enable the Fuel Pump (FP) (6/31) to build up pressure.
