Fuel Pressure Release: Service and Repair

Fuel Pressure Relieving

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

1. Remove PGM-FI main relay 2 (A) from the auxiliary under-hood fuse/relay box (to the left of the 12 volt battery).





2. Start the engine, and let it idle until it stalls.

NOTE: If any DTCs are stored, clear and ignore them.

3. Turn the ignition switch to LOCK (0).

4. Remove the fuel fill cap to relieve the pressure in the fuel tank.

5. Do the 12 volt battery terminal disconnection procedure Procedures.

6. Remove the bracket (A) and the quick-connect fitting cover (B).





7. Check the fuel quick-connect fitting for dirt, and clean it if needed.

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






9. 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:

- 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 (F) must be replaced with a new one.
