Ok when i parked my 300 it was running fine, then when I go to start it, it won't start. The first thing I did was put a new fuse in, that wasn't it. So then I checked my solonoid it was fine because when I tried it would fire but not start, so then I got thinking maybe gas but that can't be it since the back light dont work. So could anyone tell me what you think would be the problem????
