I would check the basics first.
When an engine wont start, there are a couple of things you must check.
1. Spark at the spark plugs
2. Fuel pressure from the fuel pump
3. Fuel injectors are operating correctly (opening).
4. Engine timing is correct (cam-crankshaft timing and ignition timing)
You'll find there will be a problem with one of these, once you identify it then diagnose the circuit or system accordingly.
