Hello,

Generally speaking, an engine will need spark, fuel and compression to be able to start.
So, if your engine just cranks over but does not start you will need to check to see if you are getting spark to the plugs, fuel to the injectors.
This could be due to a bad fuel pump or faulty ignition coil or module.

Can you hear the fuel pump come on when the key is in the on position?
Have you got a chance to check for spark?

Take a look at this helpful guide, it covers the typical issues:

Let me know what you find or if you have any questions.
Thank you.
