If lucky might not be timing belt.

Take off oil fill cap and have someone try to start while you look the see if anything moving in there. If it is then you more likely have cam sensor gone bad or snow/water got into ignition system.

FYI
-timing belt controls how engine parts move and keeps them in sync. If it goes the engine may need major overhaul - depending on how bad internal engine parts hit each other (replace every 70k miles)
-serpentine belt runs power steering, AC, alternator and such. You can still go but not far. And all that needs replacing is the belt.

Try to find a garage that knows something about swedish cars - it is your best bet.

If car needs replacing looking for dog sled?
