My 2004 hyundai sonata will not crank. It turns over but won't catch.

Check to see if getting spark or fuel if no spark could be crank sensor or cam sensor have to check voltage out of wiring harness if low voltage ecm bad. Pull both coil wires off coil and have someone turn ignition no spark probably ecm. For fuel check number one plug see if wet and also listen when you turn key for fuel pump. If driving it just died on ya and battery went dead like know and you tried jumping or replacing battery.Still would not start ecm bad.
