Fuel gel issue? Help

So here's the thing, I live in ND and we've had a nasty cold snap this week. The truck had been sitting for a few days plugged in with number 2 fuel in it. I put power services diesel kleen white bottle on top of the fuel so it didn't properly mix I don't think. It started this morning just fine. I came back two hours later and it wasn't running. Hesitated to start again and made it
A mile before starting again. I pulled the secondary fuel filter and added 911 to it and to the tank. Truck threw two codes on my HS BLACK MAX one was low fuel rail pressure one low injector pressure whole
Cranking. Let it sit for most of the day today started it right up it ran for ten minutes then died. Primed the fuel system up with the ignition and got it going again then died. drained water separator and and got same results. I am going to try and get it in a heated shop tonight and change fuel filters in the morning. The truck has an aftermarket exhaust but I noticed the dpf sensor is hooked into exhaust but I'm pretty sure the dpf has been deleted as I have a tuner in the truck. It does still have the EGR installed. I am hoping I don't have a fuel pump or injector issue. The truck only has 70k on it.

Any input or questions would be much appreciated. It is -45 here with the wind chill so it would be nice to get this thing running again. Thanks

I had similar problem with mine last winter. Happened one time and after changing filters outside when it was -30 said to heck with it and only run #1 fuel when it gets below 0. Yes it does cost more to run but its cheaper than having it gel up and risking problems down the road.

PS. I had a 50-50 blend of #1 and #2 when mine started to gel used Diesel 911 to get it ungeled

Mine gelled last week too. I also got the same codes as you, although not at the same time. I got the low rail pressure code when it died. Once I got it all cleaned out and new filters in, I got the low injector pressure while cranking. After a couple tries it started rough, with a little help from my foot on the accelerator pedal, but once it was up it was fine. Hopefully yours is fine too.

The secondary filter isn't the one that gelled on mine though, it was totally fine. The primary filter, the lower one on the frame rail, was where the problem was. It was covered with crap. Change your filters, especially the lower filter, and I bet things get a lot better.

The water separator is before the filter, so it'll work fine even if your filter is completely plugged (which it probably is).

I use the white bottle of Power Service too. It didn't keep it from gelling, and it was only -6 here.
