Starting issues car cranks but no start

[blackcar]

Car cranks but doesn't start. Plugged in OBD2 and no codes show up. l pressed Schraeder valve on the fuel rail there is definitely fuel pressure.
When crank is spinning the RPM gauge moves smoothly so I don't thinks its the crank sensor. I am thinking relays but wouldn't that show up on the OBD scanner?
Can someone give me good input on this issue?

Check the fuse that controls the alarm.
I once had that fuse blown couldn’t figure it out until we replaced it
