Fuel Pump Operating Voltage Inspection


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

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).
