please help...if it's not one thing it's another....

sorry, I have a 75 dodge dart /6...points...don't know how to hot wire it...I do not know how to check it for spark, i'm a newbie...my dad said to shoot some starter fluid in it and see if it starts then that would mean I'm getting a spark so we were going to do that tomorrow. oh yeah, my car has ac so the heater core was in the middle of the dash
