It is typically a fuel or a spark problem. First, I think you should try to ascertain which it is. Pull a plug, ground it to the engine, turn it over and see if you are getting spark. Then, listen to hear if the fuel pump "starts" when you turn the key to the "on" position.
I take it there is gas in the tank. 7-8 months is a long time to leave it.
Start with the basics - fuel and spark - and see where that leads you.
Good luck......
