Spark, Fuel, Air ...
1. You've confirmed the engine turns over
2. Pull the fuel line from the fuel filter to the fuel rail -- crank and confirm that you've got fuel pressure
3. No fuel pressure - pull the back seat bottom and check to see if you're getting voltage at the pump when the key is on
4. Voltage good? yeah, replace the pump
5. No voltage? start back tracking the circuit
6. Good Fuel pressure at the fuel rail? start checking your sensors that will prevent correct spark events -- temp sensor, crank sensor, cam sensors -- you're looking for the correct resistance across each sensor. If you're lucky and can acquire them, replace them - one at a time - checking to see if it will start after each replacement.
Good luck with it!
