I have 3 problems with my car, I will try to explain to you whats going on...

1.) I recently on accident slowly hit a curb at a store, and immediately my check engine light came on. A couple of days later I stopped at a stop sign and heard a very loud "knock" from under my car (possibly engine area or chassis), and my car immediately shut off. What could this be?

2.) ONLY when I TURN OFF my engine, I hear a clicking/clacking noise coming from the engine. It does not sound loud or bad enough to make me wanna cringe but it is obvious. I am unsure where to narrow this noise down to.

3.) I recently got into my car and freaked out because I thought someone had stole my gas straight out of my tank. I filled up the day before and now I am only half full... When I went into a store and returned to my car and turned the engine over, my gas needle and digital readout were increasing significantly, and at a point was fluctuating between gas miles 265-285.

These issues have me so frustrated its not even funny, so I would really appreciate it if you all would look over my post one more time and tell me if you can help. I will be more than glad to give any additional information that I can. Thank you

 

well i would first suggest to get your codes read. . . WE cannot go much further without those. Though i would lean towards ur fuelpump going out or even a clogged fliter for starters.
