Ok I turn the ignition on and let the fuel pump do its thing. Then I turn the key and the car wil crank and crank and then thump real hard like it wants to turn over but it doesnt. It goes back to cranking. Ive changed the oil put new plugs and insulators in it. But the first plug on passenger side has oil in it and every time you pull the plug out its caked in oil. Changed the fuel filter as well. The lady I bought it off of said its been sitting all winter. If you could please give me some sort of advice ive tried everything I know. Thanks!
