I assume the battery is healthy and the starter is turning over the motor strongly? If yes, if you spray startup fluid or throttle body cleaner into the intake, does it start up briefly? If no, I’m with you. If yes, it is a fuel delivery issue. Check your fuel pump fuse and swap the relay in the under hood fuse box with another known working one (horn etc). Finally, are there any check engine light\codes to be had?

I just went through this recently. It was my fuel pump...no codes or warnings either, pump just shit the bed and I couldn’t start the Jeep.
