A vehicle needs fuel and spark to run. If the vehicle isn't running, then it is not getting either fuel or spark. You can use a test light or spark tester to check for spark. The spark plugs attach to plug wires. The wires attach to coil packs which is mounted on ignition module. The module has wires that go to crank shaft position sensor which provides power for the spark. You can test sensor with an ohmmeter to see if there is resistance. If not, it needs to be replaced.
Fuel is from fuel pump, through fuel filter and through fuel pressure regulator to fuel rail, then to the injectors.
On the fuel rail, there is a test port, You can place a rag over the test port and press the valve in. There should be lots of fuel pressure. Or you can use fuel pressure tester.
Also, when you turn key to ON position, you should hear the pump turn on for a few seconds. If you cannot hear it, then check the relay with an ohmmeter to see if it is good. You can use a voltmeter and check power to the relay and to the pump as well. Check fuses if needed.

The first thing you should do, is check for battery power and ensure your instrument cluster lights come on when you turn your key to ON.
It's possible you have an issue with your starter motor, ignition switch or even the crank/cam sensor.
Have your diagnostic codes read by your local dealership or a mobile auto electrician, as this should immediately identify where the problem lies.
