im working on my friends 2002 legacy l wagon
today half of the coil pack stopped producing spark. I tried another coil pack and the problem persists. im thinking that it is an issue with ecu or the wiring to the coil pack. does anyone have a wire diagram for this car either for ecu or ignition system? or maybe a different solution to my problem? its cyl 3 and 4 on the coil pack that does not work.
also this is my first post here on the forums ..thanks for having me!
