Sadly, it takes a shit ton of energy to get things to the sun. Everything is moving very quickly around the sun. You need the opposite amount of energy to fall in.
You only need enough energy to get it down to the orbit of Venus, plus a little bit extra for some gravity assists around Venus and Jupiter. Those will shoot it to the edge of the solar system where a tiny bit of thrust will kill the remaining angular momentum and let it fall back into the sun.
Oh, and it will take a century.
