2004 F-250 FICM test - Smoke?

Background: I got a P0282 and P0611. Some rough starting, better when plugged in. I added two bottles of Rev-X about 2 weeks ago.
FICM Test Key on, engine off - about 46-47V. Dropped to 26 during glow plug cycle, then came back to mid 40s. Around 57V running.
After reading some threads here, I disconnected the small power lead on the passenger side battery to try to disable the glow plugs. I cranked it with this wire off and got quite a bit of smoke from the rear of the engine, near the turbo (not the FICM). Not sure where this came from. It cranked for 10-15 seconds using remote start, kinda smelled like fuel. I reassembled everything and drove it, seems fine. I did not touch the probe to the case on the FICM. I got a code for each glow plug (no surprise) and another P0611 for the FICM performance. I may try to re-solder the joints next week.
Questions:
Where could this smoke have come from?
Could the engine have "loaded up" from the key cycles?
How do you crank it and not start it?
Would a reflash help anything? The latest tag under the hood has a 2004 PCM update date.

THANKS!
