Pumping the accelerator pedal will only push fuel into the carburetor if there is gasoline in the float bowl. there is a sight glass on the front side of the carburetor. When my '85 sits for a while, I have to crank the engine a few times, then pump the accelerator pedal, then crank again (and maybe repeat) to get it to run.
check to make sure you have fuel getting to the carburetor. another option would be to spray some starter fluid into the top of the carburetor. If it starts but won't stay running, that might be a fuel delivery problem. If it won't start at all, then you need to check other things like ignition (spark), etc.
