1992 Saturn SC1 Won't start

I just bought this car a week ago, it drove to my house fine, just ran out of gas just about here. I have had it in my driveway for about a week and a half now. My boyfriend tried to hook up a new radio and clipped the wire harness attached to the back of the radio before disconnecting the battery. It sparked and the battery went dead. The car would only multiple click and not start. I took the battery to an auto store and had it charged. Now the car doesn't click but it won't start. It's trying to turn over but it sounds like it's not getting gas. I added gas and it still won't start. Could my gas line possibly be frozen (it's snow weather here) or do I have a major electrical problem now?
