I have a 1992 cavalier. I know something about cars but not much so I will do my best. First the starter went out so I got that replaced. Then my battery was dead so I had that tested and they said I needed a new one. Did that. After I did that though my battery light was on in my car, never was before. NOW, the battery is dead, I can pop it and it will start and run for about a minute and then it just dies. It won't keep running. I am not usre what to do next. I replaced the alternator about a year ago...with a used one. I don't know what to do and really need some sort of help. Thank you.
