I have a 2013 Dodge dart, the engine has really hard knocking

What is your question?

I have a2013 Dodge dart, base model, I got a railroad crossing and jumped and slammed my car down, now as a major knock in it, I can't drive it anywhere, it's not making power, what should I do next, the car has never had any problems the entire 4 years I've owned, some say oil pump and some say engine, any input would help

What makes this problem better or worse?

I don't start it at all

How long has your 2013 Dodge Dart had this problem?

Three weeks
