Just an FYI, I started my truck yesterday and while it was warming up in the driveway I got the low fuel pressure warning. Decided not to drive it just in case, being it's so cold I didn't want to get stranded anywhere. Brought the truck in first thing this morning and after some testing the tech found the fuel pressure sensor bad. Tech found no traces of fuel gelling. Waiting on parts, truck will be repaired tomorrow. I kept thinking that I was having a fuel issue, but the other trucks who filled up with fuel from our onsite tank are having no problems.

I've been driving my truck for close to a week getting this message, lol. Today, at -22F, I did not get the message. I'm thinking maybe the problem is solved. But I did find evidence of frozen fuel in my frame filter.
One thing I have noticed, if you're going to get either message (low pressure or engine power reduced) it seems to happen right off, not halfway through a trip.
The fuel cooler functions as a heater in cold temps and should eventually bring the fuel temp up to help melt off any waxing or gelling as you keep driving the truck. Then again, it functions on the low-temp secondary cooling system, and it seems the coolant sure doesn't warm up much in these bitter cold conditions.
It was 11* with a wind chill below 8 (f) when we left Virginia and we saw temps as low as 2* (feels like was -4 and lower).
we drove 19 hrs and saw it barely reaching into the 20s.
I'm guessing this all sounds like SUMMER to some of you guys - but i was concerned since i was reading this thread and had no anti-gel additive
I snapped a quick pic of the temp on my way in to work this AM. Definitely a lot colder than what you experienced, bushpilot.
I think if you are only going to experience cold for a day or two, no big deal. It will thaw out! But if sustained, it can be a major problem. Properly treated fuel should actually prevent you from needing anti-gel. I suspect some fuel was not being blended with enough Arctic #1 diesel in my area of the country where sustained double-digit below zero lows are rare.
Unreal. The dealer said my fuel gelled. My temps are not at all like most of you post. The truck has sat since Saturday but compared to the temps you've stated mine pale in comparison. Sunday it was 8 and Monday it was 5. I guess I'm nieve. I thought gas companies put antigel in the diesel already?? Lesson learned. Temps that cold a rare in DE.
So my truck wouldn’t start on Christmas Eve. I thought I had a fuel gel issue so I took the time to heat both filters and buggered around for two hours. It finally started so I went to town and grabbed some anti gel and filled up. It did the same thing again the next day but after screwing around again it started. I changed out the fuel filters yesterday but noticed when I cycled the key it took several times before the pump started in the tank. It sounded like crap. This morning I tried starting the truck and same issue just kept cranking. I cycled the key several times and finally the pump in the tank started, the truck then fired right up. Anyone else have this,
Update on mine, took it to the dealer today. They found the high pressure fuel pump is no good. They ordered in a new one for tomorrow.

If the high pressure pump failed, I'd be very concerned about metal shavings and debris from the failed pump continuing down the fuel rail and depositing metal in or at the injectors. This could become a very expensive failure down the road.
Typically, when the HPFP fails, the injectors are replaced and the entire fuel system cleaned. The total cost usually falls on either side of $10k.

I will have that discussion with them today, thank you for the heads up.
UPDATE. When I questioned them on the HPFP they had the Service Manager call me back. He said the Service Writer was mistaken and it was the pump in the tank that needed replaced, as I had diagnosed. Still don’t have my truck back but at least they are on the right track now.

Reason: Update
I'd like to thank all of you in this thread for posting. Though it hasn't been as cold here in SEVA, we are looking at single-digit temps this weekend (on the positive side of 0°F). After reading of your troubles with the cold, I stopped at my dealer yesterday, bought a bottle of PM23A and poured 25% of it in my tank when I refueled. Hopefully, I will not experience the troubles y'all have had. Again, THANKS for sharing your stories!

I gelled up this past weekend. Had a full bottle of white power service in my tank already and still jelled up. I read on the bottle it's only good to -30 and we were in Brantingham NY it was -34. I wasn't aware at the time so I put a bottle of red 911 in and towed it to a heated garage and plugged it in. Being 8pm on New Year's Eve no one was open to get a set of filters. Let it sit in the garage (45 degrees) over night and started rt up and ran fine but the check engine light won't go off. It's been a constant 10 during the day back home and below zero at night. I am going to get a set of filters tomorrow and change them to see if that will make the cel go off. If not it's gonna have to go to the dealer.
I cannot hardly imagine what -34* feels like. Crap if it's under 60* here it starts getting too darn cold. Right now about 39* and not going outside unless absolutely necessary.
