Why won't my car start. Starting/Stalling issues.
I have a 97 Buick Lesabre. I just tried to start my car and it acted like it was out of gas so I got 2 gallons of gas and put it in there. Now my car occasionally will start but shuts off almost instantly after. I recently hit a tire on the interstate it beat on my undercarriage pretty badly. I have been hearing a noise like a bang on the back of my trunk, like someone is closing a door right by my car while driving and sometimes right after I shut off my car. Any ideas or what other info might be needed?
