      *1 Injection Pump Drive Gear

      To insert the fuel supply pump assembly shaft in the injection pump drive gear, it may be necessary to turn the fuel supply pump assembly several degrees so that the spline indicated by the arrow in the illustration and the groove in the fuel supply pump assembly shaft are aligned. Then rotate the fuel supply pump assembly back to the position where the screw can be installed.

    3. Install the fuel supply pump assembly to the cylinder block.

      Note

      Do not damage the shaft, especially the taper.

  3. INSPECT FOR FUEL LEAK


    1. Check fuel pump operation.


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON and turn the GTS on.

        Note

        Do not start the engine.

      3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of FPC (EU5).

      4. Check for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the No. 1 integration relay, fuel suction with pump and gauge tube assembly, ECM and wiring connectors.

    2. Inspect for fuel leaks.


      1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

    3. Turn the ignition switch off.

    4. Disconnect the GTS from the DLC3.
