Hello !!

First at all check for spark on the spark plugs and see if it's any...

(remove a spark plug and attach an spark tester or an screwdriver close to ground and "crank" the engine (do it with care!)

Please check out this video.

if there is no spark the crankshaft angle sensor is a common problem for this.
