Ok did a little testing with volt meter from neutral on battery to each green / orange injector wire with engine running and get 13.9 on all wires. Also used a basic test light with engine running and test light is on and bright to each g/o wire. When I use test light on the other wire I get a dim light that flickers or blinks. I would assume that is firing. Not sure how to do test on the pcm or where and what that is.
