  1. CHECK FUEL PUMP POWER SUPPLY CIRCUIT-I
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Turn ignition switch ON.
    4. Check the voltage between ECM harness connector and ground.
      ECM Ground Voltage
      Connector Terminal
      F7 14 Ground Battery voltage

      Is the inspection result normal? 

      YES: GO TO  4.

      NO: GO TO 2.

  2. CHECK FUEL PUMP POWER SUPPLY CIRCUIT-II
    1. Turn ignition switch OFF.
    2. Disconnect IPDM E/R harness connector E13.
    3. Check the continuity between IPDM E/R harness connector and ECM harness connector.
      ECM IPDM E/R Continuity
      Connector Terminal Connector Terminal
      F7 14 E13 33 Existed

      Is the inspection result normal? 

      YES: GO TO  9.

      NO: GO TO 3.

  3. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness connectors E6, F123
    • IPDM E/R connector E13
    • Harness for open or short between ECM and IPDM E/R

    : Repair open circuit or short to ground or short to power in harness or connectors.

  4. CHECK 15 A FUSE
    1. Disconnect 15 A fuse (No. 57) from IPDM E/R. For the fuse number, refer to "WIRING DIAGRAM - ENGINE CONTROL SYSTEM - ". For the fuse arrangement, refer to "FUSE, CONNECTOR AND TERMINAL ARRANGEMENT ".
    2. Check 15 A fuse.

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Replace fuse.

  5. CHECK FUEL PUMP POWER SUPPLY CIRCUIT-III
    1. Disconnect "fuel level sensor unit and fuel pump" harness connector.
    2. Check the continuity between IPDM E/R harness connector and "fuel level sensor unit and fuel pump" and ground.
      IPDM E/R Fuel level sensor unit and fuel pump Continuity
      Connector Terminal Connector Terminal
      E14 46 B40 5 Existed

      Is the inspection result normal? 

      YES: GO TO  7.

      NO: GO TO 6.

  6. DETECT MALFUNCTIONING PART

    Check the following.

    • Harness connectors E105, M77
    • Harness connectors M11, B1
    • Harness for open or short between "fuel level sensor unit and fuel pump" and IPDM E/R

    : Repair open circuit or short to ground or short to power in harness or connectors.

  7. CHECK FUEL PUMP GROUND CIRCUIT
    1. Check the continuity between "fuel level sensor unit and fuel pump" and ground.
      Fuel level sensor unit and fuel pump Ground Continuity
      Connector Terminal
      B40 3 Ground Existed
    2. Also heck harness for short to power.

      Is the inspection result normal? 

      YES: GO TO 8.

      NO: Repair open circuit or short to power in harness or connectors.

  8. CHECK FUEL PUMP

    Refer to "COMPONENT INSPECTION ".
