Electrical problem
1992 GMC Jimmy 6 cyl Two Wheel Drive Automatic

One of the injectors is not working, there is no power going to it. Do the injectors have seperate fuses for each one? And, if not. how do I find the problem?

My information shows both the injectors get voltage from the same source.

You might try unplugging both connectors for the injector/s, then turn the key on, check for voltage at both plugs?

If there is still no voltage for the one injector, then you will need to backtrack the voltage feed for that one injector.

The voltage feed should be red for one injector and white for the other.
