Fuel Pressure Relieving

 11-48  

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

  1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.
  2. Turn the ignition switch OFF.
  3. Remove the glove box, refer to the '01 Civic Shop Manual on this CD (see page 20-220), then remove the PGM-Fl main relay 2 (A).

  1. Start the engine and let it idle until it stalls.

NOTE: The DTCs or Temporary DTCs P0301, P0302, P0303, P0304 may come on during this procedure. If any DTCs are stored, ignore them.

  1. Turn the ignition switch OFF.
  2. Remove the fuel fill cap and relieve fuel pressure in the fuel tank.
  3. Disconnect the negative cable from the battery.
  4. Remove the quick-connect fitting cover (A).

  1. Check the fuel quick-connect fitting for dirt and clean if necessary.
  1. Place a rag or shop towel over the quick-connect fitting (A).

  1. 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 pawls (D). Pull the connector off.

NOTE:

  • Prevent the remaining fuel in the fuel feed pipe or hose from flowing out with a rag or shop towel.
  • Be careful not to damage the pipe (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 pipe; once removed, the retainer must be replaced with a new one.

  1. After disconnecting the quick-connect fitting, check it for dirt or damage, refer to the '01 Civic Shop Manual on this CD (see step 4 on page 11-435).
