My Cadillac ran out of gas the other day, and when I put gas in it to restart it the engine wouldnt start. It kept turning over but eventually ended up clicking. The next day I went out and tried again, and it was turning over. I jumped the car, still car wont start. I have heard people say this could mean the end of my caddy, and I have no idea what is wrong with it. Anyone have any idea or can help me out a little to figure out what's going on?
