First I would double check and clean all of your battery and ground connections and try it again..
And a Big Welcome to the Forum.. stick with us .. we will figure it out..

 

I bet your batteries are DEAD dead.... take 'em out and have them load tested. (Wouldn't hurt to check the alternator, too.)

Fuses (ALL) checked good?
Oil Level good?
Fuel in fuel bowl?
Does your tach move when you crank it?

 

What they said^^^^^

The batteries MUST be at a minimum of 10.4 volts WHILE cranking or it won't fire. If you are going to jump start it, let it site for quite some time before trying to start. Get as much juice as you can into the batteries.
