Just for my clarification, Are you saying, the starter motor won't crank the engine or it cranks good, but, won't start? If the latter, make sure battery has a full charge and connections all good. Have a helper crank it while you visually check for spark at the plugs- -proper fuel pressure and fuel injector pulse. Any applicable trouble codes? Now if starter motor won't crank the engine, I'll post a starter motor wiring diagram and we can do some testing. Note the diagram, there are the voltage and ground circuits--starter motor--neutral switch and other. Usually with testing we can bypass several components just to see if starter motor will crank the engine. Any testing, make sure vehicle can't move.
