Fuel Pump Operation Inspection

Remove the fuel-filler cap.
Switch the ignition to ON.
Turn the fuel pump relay from off to on using the PCM PID FP and inspect if the fuel pump operation sound is heard.
- If no operation sounds is heard, go to the next step.
Measure the voltage at fuel pump unit terminal B (wiring harness-side).
Specification
- B+ (Ignition switch at on)
  - If the voltage is as specified, inspect the following:
    - Fuel pump continuity
    - Fuel pump ground
  - If not as specified, inspect the following:
    - Fuel pump relay (See RELAY INSPECTION .)
    - Wiring harness connector (Battery positive terminal-Fuel pump relay-Fuel pump)
    - Wiring harness between fuel pump relay and PCM terminal 1BI
