I bought a 88 honda civic three days ago from a personal owner. When I test drove it, it ran great. Last night while driving it, it died on me and then would not start up again. There is a random switch on the dashboard that I thought might be a kill switch but when i flipped it, whild driving, it did not kill the engine. The car sounds like it's trying to turn over, but it won't. Also this morning it sounds really sick, like it just got worse over night. I did bust my radiator last night after it died by trying to pull it home instead of calling a tow. I'll get the radiator replaced but what else could be causing my car not to start?
