truck wont cold start

[mustangman02232]

so last night i drove home normally from work, parked the truck, and passed out after the blizzard we had and being up for 3 days, this morning i woke up, went to start the truck, it was 2* outside at 10:30. truck wasnt plugged in, let the plugs cycle twice, cranked over, and seems like it breifly caught, and stopped, did it again and it the same thing. Im thinking the fuel is gelled but i know my 6.0 is not as simple as my old IDI was so i figured id as a second opinion, oil+fuel is done within 1500 miles, new batts, etc never had a problem with the truck. were supposed to get snow again tonight so i kinda need it.

FICM was tested a while back and was within spec

My thought would be the same as yours. Geled fuel. I am guessing you didnt have any additives in their?

powerservice white bottle, i just put the 911 in there and plugged the truck in, is this going to do any damage to the motor/injectors etc?

No that is good stuff won't hurt a thing. It is a good idea to change the fuel filter if it is gelled up though. Has it started in that cold of temps without problems in the past? Because my 7.3 won't start at that temp unless it is plugged in, mine will only start down to about 10 degrees when not plugged in.

not this year, it did last year about -5* and it was kinda rought, and it only sat for about 9 hours., and there is another 25k on it since then, its been sitting for a good 14-15 hours now. i have an extra racor filter so ill do that, is there any harm in changing them in the cold temp with those stupid plastic caps or will it be ok to drive it 6 miles to my uncles shop and do it there? injectors and pumps shouldnt have a problem after the gelled fuel?

If it will start and run it is fine to drive for a while but that wax builds up on the filters and I don't think it comes back out of the filters. That short distance should not hurt anything though if it will start, yeah messing with plastic caps at that temp could prove to be a pain.
