Engine will not start or crank

After it sat there for three days I walked out got in it turned the key and it started right up. I tried it several times after that and it started every time. I do not know what was wrong, but to me it sounds like the ignition switch is going out on it. It had power every where but the starter and ignition switch where the wire going to the starter comes out may be wrong, but after three days of reading everything I could find on the internet that is the only thing I can think of it being. They cut way too many corners making that car just trying to get more money in their pockets.
