My '03 A/T Forester X stopped running last week. It began stumbling and then it died. Now it's refusing to fire on 3 and 4. The coil pack was replaced about a year ago. Wouldn't you know it---I threw away the old one (which still worked) two weeks ago.
I figured out from swapping wires that it's either the coil pack or the wiring that leads to it. Is there anything that could go out suddenly like that and cause this problem? Perhaps a fuse that runs half of the ignition or a sensor that may have lost its engine pulse?
I checked the primary resistance on the coil pack and I'm getting no continuity between 1 and 2, and the continuity between 2 and 4 is in spec. This confuses me, since the lack of connection between 1 and 2 should indicate that the front cylinders aren't firing. Am I reading that wrong?
Thanks
