I am not sure if adding coolant has anything to do with the no start problem. I bought the car and have not run it very much as I have not had time to go through and do a basic tune up. But when I did run it the other day I noticed a couple of things. First, I noticed that the call smelled of gas and that the exhaust smelled like gas. Second I notice that the temperature gauge would shoot up to almost red and then come back down to midway. To try and tackle these problems this morning I decided to start the car and see if I could track down the fuel smell issue. I drove the car around the block and did not notice much of the same fuel smell I smelled before. So, I parked the car, popped the hood and checked the coolant. The tank was completely empty. I noticed a little coolant behind the coolant pump. So I went to AutoZone bought some coolant filled up the tank and then try to start the car and now it won't start. The car cranks but is acting almost like there is no spark. So I pulled the spark plugs. They were wet and smelled like gas. I bought new plugs. Still no luck. I'm a little stumped as I hadn't had any stalling issues or hard starts prior to this. Any help will be much appreciated.
