Fuel Pump Control Circuit
DESCRIPTION
The FUEL PUMP relay switches the fuel pump speed according to the engine
conditions. The fuel pump
operates when the ECM receives the starter-operating signal (STA) and
crankshaft-rotating signal (NE).
The FUEL PUMP relay is turned ON while the engine is idling or operating at l ...
