Fuel Pump Operation Inspection
1. Connect the SST (NGS tester) to the DLC-2.
2. Remove the fuel-filler cap.
3. Turn the ignition switch on.
4. Select the SIMULATION TEST function on the NGS display.
5. Turn the fuel pump relay from off to on using the FP RLY PID and inspect if the operation sound is heard.
- If no operation sound is heard proceed to Step 6.
6. Measure the voltage at harness side fuel pump connector terminal B.
Specification: B+ (Ignition switch is 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 80
- If not as specified, inspect the following:
- Fuel pump relay
- Wiring harness and connector
