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.
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.
