For sure, change the filters.
Mine gelled up last February when it got to -14F in Kansas City.
I had it plugged in and ran fine on remote start for 10 min.
I got less than 2 miles down the road and started having trouble.
I have the BMP Cat filter kit.
Engine mounted filter was fine opened up the rear and found this.
I have installed the rear heater element and a fuel pressure gauge on the front housing right before the high-pressure fuel pump.
