Trouble getting spark to rear trailing plug

[tweiss3]

That may be the only thing left to check. The last thing before going that route would be to make sure the connector to the ECU is fully plugged in and didn't for some reason back out. Also check fuses, cause you never know.

I do feel you on doing the work outside, I had to replace the oil cooler lines while it was below zero, outside in the snow.

If you lost power or disconnecting electrical plugs, there's a 50 / 50 chance it'll kill the trailings.
Easy indication of this is your tach will not move (when cranking).

How did you check the trailing spark?
Did you eliminate the spark plugs?
Easy test is to shove a small screwdriver into the spark plug end of the wire and put it close to a known, good ground spot - does that spark when you crank?
If you're trying to test with the spark plugs, it's a good chance your spark plugs are "dead".
You mention putting oil in the engine - the oil can kill the spark plugs.
Dead spark plugs will not fire.
