Hello,

You will need first see if the engine is getting spark and fuel.
Test for spark to plugs. You can just simply take out a plug and check if it produces spark when the engine gets cranked.

It is has spark check for fuel to the injectors. Can you hear your fuel pump come on?
If the pump does not come on, then it could be a fuel pump relay or a bad pump.
Check the relay, it is located under the dash on the left-hand side (see attached picture).
Inspect for any corrosion or bunt pin(s).
This relay can also be tested:

If the relay is good then check for power to the fuel pump, if there is power then the pump is likely bad.

I have attached the fuel pump testing procedure below.

Please let me know of any questions.
Thank you.
