Fuel Pump Operation Inspection

1. Remove the fuel-filler cap.
2. Switch the ignition to ON.
3. Turn the fuel pump relay from off to on using the FP PID and inspect if the operation sound is heard. (See ON-BOARD DIAGNOSTIC TEST .)
   • If no operation sounds is heard, proceed to next step.
4. Measure voltage at wiring harness side fuel pump terminal B

Specification 

• B+ (Ignition at on) 

• If the voltage is as specified, inspect the following:
  • Fuel pump continuity
  • Fuel pump ground
  • Wiring harness between fuel pump relay and PCM terminal 1BG
• If not as specified, inspect the following:

• Fuel pump relay (See RELAY INSPECTION .)
• Wiring harness connector (Main relays-Fuel pump relay-Fuel pump)
