i have a 1987 honda civic, the problem is that it wont turn on. i was driving one day and it just turned off for no reason. the car had gas, oil, and water. the day before it was overheating and it was low on oil, but i put oil that same day. the only problems i know is that it wont pass the smog check and it was leaking the anti freeze. does anybody know what could be wrong with it? someone told me it was the timing belt but i wasnt sure.
