2013 Toyota Corolla turns over but won't start

#1
My car was working perfectly fine yesterday. I went to get in it today and I'm feeling and hearing it turn on the engine side. I do not know much about cars I'm being told all kinds of stuff. I did test the battery it has 14 volts. I'm being told it could be the Crankshaft position sensor. My car only has 111k miles on it. Please help me. I am completely lost and tommorow I am towing it to a local shop. I want to have my questions ready to ask them. OBD2 doesn't pull any errors.

Turn key - crankshaft turns over but doesn't start.
