the vehicle is not starting because it is not getting spark or not getting fuel.
No spark would most commonly be caused by a bad crank sensor, bad main relay or bad engine control unit.
No fuel would be caused by a blown fuel pump fuse, bad fuel pump relay (rare), or bad fuel pump.
Depending on your abilities and equipment/tools, you may or may not be able to diagnose further.
The simplest thing to do (after checking the fuel pump fuse) would be to spray quick start / starter fluid into the intake (carefully) while cranking. If the engine starts on this, then you have spark and the problem lies with fuel delivery and can be further traced from there.
Another check would be for power at the fuel pump, and to see if it is running or not. If power is present and it is not running, it is confirmed as having failed.
If I had to give a guess, I would say it is likely a bad fuel pump.
If you are not comfortable or familiar with the above then the testing should be carried out professionally.
