1992 Nissan Maxima Car won't start

My car will not start or even turn over. No clicking sound or anything. It was running fine the last few times but there was a sound like gas escaping from the left side of the engine when I started the car. No smoke or smell to it either. Thought it could have been a hose but checked later and couldn't see any loose hoses. Next time I went to start the car it wouldn't start. The battery is fairly new and the alternator was fine at the time when I replaced the battery. I have not tested the fuses yet. I can't seem to figure out where the problem is. Perhaps the starter or something electrical but it doesn't explain the gassy sounds. Please help. Thank you.
