Does this injector have fuses,
Expert:  Daniel Wilson replied 1 year ago.
No it does not. The injectors are fired from the injector drivers in the ECM. High voltage is delivered from the ECM to the injectors through the injector harness.

I have the same problem on #4. #5. #6 fuel injectors
Expert:  Daniel Wilson replied 1 year ago.
Thanks for the update. That is an indication of faulty injector drivers inside the ECM. The ECM will need to be replaced if the harness checks good between the ECM and injector solenoids.
