  1. Ignition/Vehicle Off, disconnect the harness connector at the G18 High Pressure Fuel Pump.
    NOTE:

    The following tests require the DMM and test leads must be calibrated to 0 Ω in order to prevent misdiagnosis.

  2. Test for 0.3 - 0.7 Ω at 20°C (68°F) between the high control circuit terminal 1 and the low control circuit terminal 2.
    • If not between 0.3 - 0.7 Ω 

      Replace the G18 High Pressure Fuel Pump.

    • Go to next step: If between 0.3 - 0.7 Ω 
  3. Test for infinite resistance between each terminal and the G18 High Pressure Fuel Pump housing.
    • If less than infinite resistance 

      Replace the G18 High Pressure Fuel Pump.
