Hello,
An engine will need spark, fuel and compression to start. Mission either of these will not allow the engine to start.

Check to see if you are getting fuel. Can you hear the fuel pump come on when you turn the key to the on position?
If the pump does not come on then you will have to check the fuel pump relay. It is located under the hood fuse box. Check the relay for any corrosion or burnt pin(s).
You can also test the relay:

If the fuel pump comes on then check if you have fuel pressure at the rail.
Here is a helpful video of how to check fuel pressure:

Inadequate fuel pressure can be cased by a clog in the line, it can be a restricted fuel filter or a bad pressure regulator that is not allowing fuel to the engine.
Please let me know of any questions.
Thank you.
