When starting my car up its constantly cranks and cranks and it will turn over and sometime I have to step on the gas in order for it to turn over all the way if that makes sense if I don't it will start like a coughing sound and then turn off but if I step on the gas most of the time it catches and will run I recently changed the crankshaft sensor and got new spark plugs and coil around the month of November why do you think that's happening and what should I do?

Lets run the codes to see if any are stored. It can be a weak fuel pump as well. Here is a guide to go over which will help us fix the hard starting issue:

Also, I would service the throttle body, here is a guide and instructions for your car in the images below.

Check out the images (below). Please let us know what happens.
