I would say the least you will need is a fresh charged battery and the necessary tools to get it installed. It doesn't really pay to try to jump start a car thats been sitting for a long time.
I would try to find out from someone how long it has been sitting. How long have the license been expired. Does it look like it has been sitting for years. Then also, I think a small can of fresh diesel and enough hose to hook into the supply line along with a fresh filter or filters. Try to keep the can of diesel above the height of the pump. If it starts hook to regular tank if fuel is present and looks and smells reasonable. Stop engine to before making fuel changeover.
I think a helper/buddy is invaluable in a situation like that. "Two edds is better then one! Watch out for snakes and vermin!


If it was easy everybody would do it!
