I have the same problem. Starts fine plugged in, below 45 or so, forget it. Sometimes won't start. Mine is going away for the winter, but I'll be interested to see what the remedy is. Never had the problem before the motor/fueling was stock. 
Tuning big injectors

- Start date
Mine starts just fine. 16.5 CR, C gaskets and 100's. I have stock rail pressure at idle, and 45mm3 of cranking quantity. Coldest it has started was 20* It didn't like it, but did just fine.
Check all temp sensors
A bad reading could change a multiplier table and you won't have the timing advance you need for cold stuff

Same here......I have been wondering if changing the glow plug timer with efi would help, but tony locked me out of the file.
Mine fired up yest a.m. at 19 degrees.. 100 overs built motor, fingers pistons. First round of tuning from Steve. It def didn't like it but fired up and hazed a bit but warmed up quick.
Coldest its been here in a while. Be in the 50s by the weekend tho. And hell no . My neighbors hate me as it is .
Mine use to do like you are taking when I ran 16 to 1 cut stick pistons. Cold weather like low 30's or 20's it did not want to start unless plugged in. Same injectors in a 17 to 1 motor didn't have a single issue. It probably is a combination of issues.

Not cold enough for gelling... I see fuel gel if its not a winter blend around 20 from personal experience. op add some glow plug time pre run also want to make sure there working right and leave it plugged in all damn night if you want it wont hurt anything.

Okay first off happy thanksgiving! Second I had a log of trying to start it but the computer died. The rail pressure was around 6500 cranking and 7200 after it finally started. It didn't take as long to start this time but still smokes while idling. Pulse width at idle is 750us. I couldn't get a reading off the glow plugs but I did set them to 25 seconds this time.
Well I ran her pretty good yesterday on tune one two and three. Guessing around 450 on one 550 ok two and 650hp o three. Third tune I blew out the o ring on the block heater and some how cracked a copper washer on injector 8. Never seen this before? Busted it into 4 pieces.
Also logged it after 10 hours of sitting and starter up just fine in 47 degree weather. Here is the log

Da fuq?? Ive never seen that either. Its almost like it was smashed down so hard that it started to tear the copper washer then the compression finally blew it out.
I've broke a copper in half. It's not fun trying to pull it out for fear of it falling into the cylinder. I used a bunch of grease on a pick to pull them out.
I've used a shop vac and a peice of fuel hose between my fingers to make the seal on the big hose and used my other hand to run the hose. Works really well to suck carbon out. Would work good for this too I'd think.
