There are so many possibilities, so - as marc34 asked - do you have pressure in the fuel rail? Do you have a spark at the plug? When you indicate that it won't start, does it turn over but not start, or does it just sit there, no starter turning, no engine turning?
If you can, when it is running, go to a local Autozone, Advance auto, or local parts store that will do a FREE FREE FREE test with a code scanner for you thru your OBD-II diagnostic connector and give you the trouble codes stored in your engine computer (call to see which one will do this). They will tell you what the code is and what it means. This will at least help isolate the intermittent start problem to a specific area. And THEN post back for a direction if you haven't fixed it by then. Good Luck!
