Make sure your fuel isn't gelling up, you have the largest, strongest battery that will fit in there with nice, big, not corroded battery cables (fast cranking is key), as well as working glow plugs. It may take a couple of glow plug cycles and a bit of cranking to get it going, but it should fire.

FYI, if you get white smoke while cranking or right after start with a very cold diesel, that's unburned fuel blowing out the exhaust, and normal until it's hitting on all cylinders. Black smoke is partially burned fuel, and can happen too.
