Kawasaki Ninja Service Manual / Fuel System (DFI) / Fuel Pump / Fuel Pump Operating Voltage Inspection

NOTE

Be sure the battery is fully charged.

Turn the ignition switch to OFF.
Remove: Fuel Tank Bolts (see Fuel Tank Removal) Fuel Tank Bracket Bolts (see Fuel Tank Removal)
Disconnect the fuel pump lead connector and connect the harness adapter [A] between these connectors as shown in the figure.

Main Harness [B] Fuel Pump [C]

Special Tool - Measuring Adapter: 57001-1700

Connect a digital meter [D] to the harness adapter leads.

Fuel Pump Operating Voltage Inspection

Fuel Pump Operating Voltage Connections to Adapter:

Digital Meter (+) → R (pump Y/R) lead

Digital Meter (–) → BK (pump BK/W) lead

Measure the operating voltage with engine stopped and with the connector joined.
Turn the engine stop switch to run position.
Turn the ignition switch to ON.

Fuel Pump Operating Voltage Inspection

Operating Voltage Standard: Battery Voltage for 3 seconds, and then 0 V

Turn the ignition switch to OFF.

If the reading stays on battery voltage and never shows 0 V, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).

If the fuel pump relay is normal, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

If there is still no battery voltage, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).

If the fuel pump relay is normal, check the wiring for continuity (see wiring diagram in this section).

Special Tool - Hand Tester: 57001-1394

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

If the reading is in specification, but the pump does not operate, replace the fuel pump (see Fuel Pump Removal/Installation).
