Fuel Pressure Release: Service and Repair
Fuel Pressure RelievingBefore disconnecting fuel lines or hoses, relieve pressure from the system by disconnecting the fuel tube/quick connect fitting in the engine compartment.
1. Turn the ignition switch OFF.
2. Remove the PGM-FI main relay 2 (A).
3. Start the engine, and let it idle until it is stalls.
NOTE: Temporary DTCs or DTCs P0301, P0302, P0303, P0304 may come on during this procedure. If any DTCs are stored, clear the DTCs with the HDS.
4. Turn the ignition switch OFF.
5. Remove the fuel fill cap, and relieve fuel pressure in the fuel tank.
6. Disconnect the negative cable from the battery.
7. Remove the quick-connect fitting cover (A), and place a rag or shop towel over the quick-connect fitting (B).
8. Check the fuel quick-connect fitting for dirt, and clean if necessary.
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 looking pawls (D). Pull the connector off.
NOTE:
- Prevent the remaining fuel in the fuel feed line or hose from flowing out with 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.
