Trouble getting spark to rear trailing plug

[tweiss3]

My FC's been sitting for the winter (as normaly, I don't drive it when there's Snow/ice/salt on the road) and the battery was old, so I charged it up to do my usual warmer weather start ritual, as it had only been sitting for less than three months, I did all the normal things to try and start it. It failed to turn over good enough to catch, and then the battery died. No prob...bought a new battery and did the usual oil in the plug holes to make sure there was compression and tried again. Nothing. It would turn over, but not start.

So after doing some diagnostics such as checking to see if the plugs were getting spark , I noticed that all but the rear trailing one was. So I swapped wires, changed coils with some spares I had, even changed the housing the trailing coils sit on in case the wiring had gone bad in them and still nothing. Every plug will light except the rear trailing and it won't fire up without it.

I'm tearing my hair out trying to figure this one out, but I'm at the end of my options. As towing it to a garage and spending way too much is not an option right now, I thought I'd turn here and see if anyone's got any suggestions. I'm open to any ideas and I'll let you know if I've tried it already. If not, I'd be happy to give it a go. As long as it doesn't involve something outrageous and out of my comfort zone ^_^ (I don't have a nice heated and large two car garage, and must do most of my work outside unless I move a lot fo crap out of the garage like the Bikes)

Anyone...help? Anything's appreciated right now.
