The first step is to properly describe the symptom, then I should be able to help if it is a starter problem. You listed the crankshaft position sensor, which applies to a crank/no-start or run problem. Then you listed a battery and starter, which implies the starter is not even spinning the engine. Those are two totally different problems that people lump together as "does not start".
If the starter is cranking the engine, but the engine does not run, the place to start is by reading and recording the diagnostic fault codes. You will need a code reader for that. Many auto parts stores rent or borrow tools. They may have one you can borrow.
