Fuel Pressure Release: Service and Repair

Fuel Pressure Relieving

Before disconnecting fuel lines or hoses, relieve pressure from the system by stopping the fuel pump and disconnecting the fuel tube/quick connect fitting in the engine compartment.

With the HDS

1. Remove the fuel fill cap.
2. Turn the ignition switch ON (II).
3. From the INSPECTION MENU of the HDS, select Fuel Pump OFF, then start the engine, and let it idle until it stalls.
4. Turn the ignition switch OFF.

NOTE:
- Do not allow the engine to idle above 1,000 rpm or the ECM/PCM will continue to operate the fuel pump.
- A DTC or a Temporary DTC may be set during this procedure. Check for DTCs, and clear them as needed.

5. Turn the ignition switch OFF.
6. Make sure you have the anti-theft codes for the radio, then write down the frequencies for the radio's preset buttons.
7. Disconnect the negative cable from the battery.




8. Remove the quick-connect fitting cover (A).
9. Check the fuel quick-connect fitting for dirt, and clean it if needed.




10. Place a rag or shop towel over the quick-connect fitting (A).




11. Disconnect the quick-connect fitting (A): Hold the connector (B) with one hand, and squeeze the retainer tabs (C) with the other hand to release them from the locking tabs (D). Pull the connector off.

NOTE:
- To prevent the remaining fuel in the fuel feed line or hose from flowing out, use a rag or shop towel.
- Be careful not to damage the line (E) or other parts.
- Do not use tools.
- If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push the connector until it comes off easily.
- Do not remove the retainer from the line; once removed, the retainer must be replaced with a new one.

12. After disconnecting the quick-connect fitting, check it for dirt or damage.
13. Reconnect the negative cable to the battery and do the following items:
- ECM/PCM idle learn procedure.
- Power window control unit reset procedure.
- Enter the anti-theft codes for the radio and the navigation system, then enter the customer's radio station presets.
