Inspection Procedure 23
Fuel pump system
Probable cause
DThe engine-ECU turns the fuel pump relay ON during cranking and engine
operation, and supplies the drive power to the fuel pump.
DWhen operating with a low load, the engine-ECU supplies power to the fuel
pump via the resistor. When operating with a high load, power is directly
supplied and the fuel pump fuel discharge amount is increased.DFuel pump relay 1 malfunction
