Message I thought I would update on my problem, as my previous thread is locked.

Original issue was I could not enter the O2 sensor monitoring mode. I would get no CEL blinks while running in Mode II. Turns out I had a broken O2 sensor wire on my right hand side, which caused the entire system to go into failsafe mode (thus, no CEL blinks). Embarrassing, but easily repaired.

Hopefully this tiny tidbit of information is found useful by someone in the future.
