Are you talking about your 5D Mk III?!? Canon has a support article for things to try. (check the AF switch, clean the contacts on the camera, make sure the lens is mounting properly, check custom functions to make sure shutter button AF isn’t disabled, etc…)
Did you somehow enable back-button focus without realizing it? Here’s a video that reviews the relevant settings for those AF options.
There’s also an official Canon AF guide for the 5D Mk III. (@jamesstaddon might find that handy too. 🙂 )
