Can you turn the engine 360 by hand using the flywheel screen?
What is the make , model and engine? You could have had oil on top of piston, and when trying to start, it caused internal damage to the engine! If engine does not turn by hand, remove spark plug and look for any evidence of damage that may have occurred .
I see question still open, did you find problem?
