You need air, fuel and ignition for an engine to run.
Check the usually suspects, applicable relays, is fuel pump priming, fuel at injector rail, inertia switch reset, clutch/neutral safety switch, spark from plug wires, no obstructions in the intake track, battery and cables, etc.
Old school methods…. Turn the steering wheel full lock and try starting (ignition switch might be going bad). If the starter is seized a lite tap with a hammer might dislodge it… push start it and see if it runs, etc.
I have to ask, any codes and how was it running prior?
