Are you using BIO diesel at all?? B-xxx I hope not...
There was a thread here where Whitmore daughter got a cummins and she got a load of BIO and in the extreme cold the BIO separated from the diesel and gelled up good.
2 cycle oil will do nothing for it... You got to use PS 911 or Kerosene... Which we all don't like to do but sometimes you got to...
The only thing I can suggest is start over and double check everything... Fuel (Type, clean, etc), Fuel lines (clean, no debris), Filters (Fresh?), Power (Good solid 12V to the pumps)... You might even test the pumps by pumping into a container (bucket)...
It's either a fuel problem or its a power problem... Not much left...
