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

     Replace the G18 High Pressure Fuel Pump.

   • 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.

   • If infinite resistance 
4. All OK
