If you have biodiesel in the tank instead of winterized diesel, the only way you are going to get it to start is to get it up to temps above the pour point of the fuel.

A drop light is a metal reflector lamp on the end of a cord, and it WILL help, even at 35 below, if you can contain the heat (fiberglass insulation will help).

An alternative is to build a charcoal briquet (not wood!) fire on a piece of sheet metal and slide it under the oil pan. With a little luck (an no breeze) this will get the engine warm enough to fire. Leave the hood open, and have a fire extinguisher handy....

A torpedo heater aimed at the radiator works well too. a o tl I've had to start reluctant diesels in cold weather?

To prevent this problem in the future, keep the car plugged in (check, don't depent on others for this!) and make SURE you have the proper oil (synthetic) and fuel (winterized diesel) in the car.

You may not get it going until it warms up. Maybe in March....
