Pull the longest spark plug lead of the plug and fit a spare plug into it.then place lead/plug so the metal of the spark plug touches the metal of the engine and crank it over.if u can see a spark jumping the end of the plug it gets complicated.If no spark then most likely the crank angle sensor has packed in.Next step if its not the c.a.s is to get it code read for next probable which would be the ignition amplifier
