I went off to college for two years and during that I left my car at home. I got back and now it doesn't run, go figure. Didn't get start it once a week like I asked... but oh well. Almost got my butt stung by the wasps that decided to make a home out of it.

In any case, what are some common problems that could be killing my car and some possible fixes I can do? I don't want to have it towed to a shop if I don't have to.

My car is an 1989 Chevy Corsica with a little over 100k miles on it.
