Hook up a fuel pressure gauge and a spark tester that you can hook to the spark plug wire and tape to your window (you can get them at most auto parts stores). Then try to start and run your car.
This test will tell you whether the problem is in the fuel system or the ignition system. After you know that you can narrow down the things that might be causing it. Let me know what the test shows.
