Component Testing

Static Test

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

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

2. Test for 9-11 Ω at 25°C (77°F) between low control circuit terminal 1 and high control circuit terminal 2.
   • If not within the specified range 

     Replace the G18 High Pressure Fuel Pump.

   • If within the specified range 
3. Test for infinite resistance between each terminal and the G18 High Pressure Fuel Pump housing/case.
   • If less than infinite 

     Replace the G18 High Pressure Fuel Pump.

   • If infinite 
4. All OK.
