Help! And yes I will be taking it to a mechanic but I wonder if someone could shed some light on my situation. I drove my car all day long and it was fine. This evening I pulled into sonic turned my car off while waiting because my gas light had recently came on, and then when I go to turn my car back on it won't start. All the lights work, however when I turned on the headlights the power to the radio would go off. When I turned the key the panel would blink and the alarm would go off. Eventually the alarm would stop going off after many tries. When turning the key I would get fast clicks. It was very odd... Please someone shine some light on what I'm going through. Is it my starter, battery, alternator??? Thanks!
