up the contacts between the coil branch/series 2 jumper harness (7-pin wire retainer type). Didn't have ground. No fire on #4 continues to be a mystery. Coil packs ohms out at .7-.8 and has continuity back to the PTU. Still scratching my head, but at least I got her to start. I'll swap coil packs just to verify that's not the culprit maybe later Sunday.
I've yet to check connections further upstream. I have a feeling that'll be fun. Again, any tips from your experience is much appreciated (thanks Peter!).
