How cold is it up there? Fuel might have gelled. Check your fuel filter, fuel pump and don't forget to make sure you have fuel. I know it sounds stupid to say, but I know from personal experience.
Hopefully it's not your injection pump. I wouldn't use a whole lot of that starting fluid. Using it as an aid is one thing, letting your engine run on it can't be too good. I'm not a mechanic, but I did stay at a Holiday Inn Express last night.
