All other cylinders are firing but 4 will not. When i pull plug wires off while it is running 1,2, and 3 make it run worse but 4 has no effect. It has spark and good compression on 4 but the injector is not working. I have replaced all injectors and still no change. I started looking into the injector wiring and found that the 2 wires going to the injector clip were cut and just twisted together. I dont know to much about the injector wiring so i have no clue where to start.


It sounds like a subaru :notgood:
 
Yes you can see it spark. The clip looks like it has been changed. it jut has 2 white wires coming off of it. going into one of the white wires is a black wire with a red tripe, and into the other is a green wire with a white tripe. I will ost pictures as soon as my camera is charged.
 
I just bought the car. In the pics i pulled all the shrink wrap off and this is what i found.
