0 fuel should set you adrift without killing you, and then have some events that only occur while drift>0 or certain probabilities are 100% when drift>0, and every turn you are drifting, the drift var increases(ie: how far off course you are), and you could get an event that gives you the fuel to get back on course. (it depends on how much food and luck you have).  0 food should also not kill you, and just have your settlers slowly die of famine. Theres always a chance to get to a food point before all your last settler succumbs to death.
