I dont know anything about cars....My cars wont start?

If you were told you were out of gas , and didn`t get any . Do you think that would matter? If you nothing about cars , and you can`t tell us more about the problem. Then us making guesses will not help. . Because you would not be able to fix it . Let the tow truck take them to the repair shop . The guys there can actually see the cars and do a better job of finding the problem.
