Start with the basics. Check for spark. For this, you can use an inline spark tester. Observe for spark during cranking. Also, check for fuel pressure. There is a test port on the fuel rail. You can attach a gauge there to check for fuel pressure.

You need THREE basic things for the engine to run:
1) Fuel and air mixture
2) Spark - at the correct time
3) compression

One of these 3 things is missing.
Let me know which one is missing, and I can give you some more help on diagnosis.

Hope I have been of some help.
