FICM issue or injector?

[jaggermouth]

I have an issue that slowly has gotten worse.
When I start the truck in the morning at around 3-5C* outside, it has a rough start and billows out grey/white smoke for about 5 minutes until it gets a little warm. The smoke smells like diesel, not coolant and I have never lost or puked out coolant from the bottle. If its a bit colder out, and I try to drive it soon after starting, it will sometimes stall.
I checked the codes with my SCT and I get p0272, an injector code from what I read but I don't seem to have injector symptoms?
This is the only issue I am having. It does not smoke while driving, it has a steady idle, and it starts great when warm.
I was thinking glow plugs as I havent tested them yet and the truck has 300,000kms but it smokes for a while after starting. Truck is all stock aside from a Looney Tune.
Just want an idea on where to look before I start testing components.
Thanks

Check your FICM voltage. If it checks good, change oil to 5w40 synthetic and get a couple bottles of Rev-X oil additive.

Rev-x could actually help this issue? I'll check the voltage if its not raining tomorrow or on the weekend if Im not working. Paranoid because I don't want to short it out by accident due to an unsteady hand haha

Get a monitor, it's essential on the 6.0. Load test your batteries too, i'm betting, ficm. Not stiction.

will do, just need to wait for the right deal

Check out the scanguage II, can't beat it for the money.

Let me know what you want/need for your truck. I'll get you hooked up!

Check your wires and connections all the way to the injector. Cold temperatures just accentuate the problem for the injector. As others have said, test the FICM. You need to do the cold hard start test ie. balance/injector test. You might be able to save it, but more than likely your injector is on the way out.

A glow plug issue would not usually cause smoking for a long time at those temperatures. Once the majority of cylinders fire and get up to speed the cold cylinders will fire as well. Sounds like the injector is remaining open for too long.

Ya,I'm thinking stiction also,I'm in cold weather,I use 5w40 Rotella T6,great starts,In sub zero weather,I have a titan oil pan heater.,you can get a 200watt magnetic oil pan heater,and see if she starts better in the mornin' with warm oil.just stick it on the pass. side of the pan and plug it in overnight. I've had cases where 90 seconds with a propane tiger torch has fired up the most stubborn 7.3 and 6.0 in cold weather.

Bought a scangauge 2 and replaced both my batteries yesterday. While cranking the FICM drops to 44v and stays around 45v until I drive it for around 10 minutes, then it stays at 46.5-48.5v.
I am leaning towards buying just the circuit board or upgrading to a 58v ficm.
Any thoughts? I can't have the truck sitting for weeks, needs be repaired the same day with no downtime.
