this happened to me recently when i ventured to indiana. After much trial and error, i unscrewed the spin-on fuel filter, filled it with diesel additive (just poured about half of the diesel out of it first. the one with the white bottle, black and red writing), primed it just enough to get most of the air out, put the rest in the tank and jumped up and down on the bumper to mix it up. The car started right up. It was sweet victory after so much cold and misery. Of course i had to give it some pedal, and keep it depressed for a little while. The next night, i parked it in a garage.
