Remove a couple of plugs and see if they are wet with petrol.

If they are take them all out and turn the engine over with your foot on the floor so to put plenty of air through the engine.

Refit them and try to start it again, a quick squirt of Easy Start before you turn it over could help.

If you have a plug in code reader you could see if you are getting an RPM when you turn the starter, it will only be 100 to 200rpm but it will tell you if the Crank Position Sensor is working.
