I noticed that last time I was in Europe. Didn't see one in 3 weeks on the continent, and back in the states, you see like 30 a day h:

Before you jump to conclusions on what to fix, run down the list:

1) Do you hear the fuel pump prime?
2) Do you get spark?
3) What's the status on your filters?
4) How's the timing on the engine?

Also, once my car wouldn't start. I pulled the negative battery terminal for 5 minutes, pluged it back on, and it's started fine ever since. Something else to check
