only happens sometime- it'll run fine shut it off then will only crank not start

What is your question?

I bought the car from a family member who used to drive it to Florida and back, me and the old owner both live in Maryland. You can start the car up fine and it will run fine (it sounds and feels like it has a misfire but it just had new plugs, wires & all put in) you can drive it for how ever long you need to & shut it off (only does it sometimes) but when you go to start it, it won't start it just cranks, I can only get it to start again by spraying starting fluid into the air filter & it fires right up I have a repair manual that shows me how to basically strip the car down to the frame and put it back together so I can probably know/get to what you are talking about if that helps
