Montana AWD V6-3.4L VIN E (2004)
Steps 6-11
The numbers below refer to the step numbers on the diagnostic table.
3. This step tests each fuel injector resistance within a specific temperature range. If any of the fuel injectors display a resistance outside of the
specified value, replace the fuel injector.
4. This step determines if all of the fuel injectors are within 3 ohms of each other. If the highest resistance value is within 3 ohms of the lowest
resistance value, then all of the fuel injector coil windings are OK.
6. This step determines if the ignition 1 voltage circuit under the intake plenum is causing the concern.
8. This step determines which fuel injector is faulty. After subtracting the highest and lowest resistance values from the average value, replace the
fuel injector that has the greatest resistance difference from the average.
