Sounds like your firing!
Be sure that your crankshaft is not wet, oil coated, or just plain out needs replacing. I'm almost certain this would fix your problem.

It does not take 3 hours to change spark plugs..I will suggest you get the right equipment to do this job.Get the right tool that can sit on the spark plug and unscrew....You will need to disconnect the coil pack that sits on top and disconnect the wires if needed.From there it is self explanatory.
