Did you check for spark ?
take the spark plug lead off and remove the spark plug
reconnect the loose spark plug to the spark plug lead - then place the spark plug on the engine and try to start - since you can see the live end of the plug - you should see a it sparking - do not touch the plug with the ignition on - or you will get a good jolt
test all spark plugs - if not here then it is probably a fuel problem

4. Spark plug cables in bad condition and leaking.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
