2012 chu has two injector faults 652,653. 652 shows open and 653 shows shorted to high. Ohm checked both injector valves, and compared to other four injectors, the harness to the ecm, and tried a know good ecm. Has anyone had injector harness failures?? The injectors and cups are only a month old, so I'm assuming the injectors are good. Haven't tried swapping injectors yet. Does anyone have any ideas or things I should be looking for?
