2001 sl2 dies?
 

My girlfriend went into the movie store and when she came back out it wouldn't start. The car turns over, the battery is fine, and the fuel pump is working. My uncle thinks it could be the crank sensor. Im kind of car illiterate so try to work with me lol.

Crankshaft Position Sensors frequently go bad on the S cars, so that is a good place to start. Usually, a defective CPS will result in a 'no spark' condition. It's easy to replace, so long as you can get to the rear of the engine, near the starter. You can test it with a multimeter- should be about 700-900 ohms.

Indeed -- check for spark -- of no spark then CPS per Hos
