So i was driving home from a car show and the car just cut off. So the next day i read the codes and it was P0335 `crankshaft position sensor` and that was it, so i replaced the sensor and now the car has no codes but it will only crank and wont start. (Sometimes the vehicle gives an effort as if it is going to start but then just dies out)

 

This kinda reminds me of a similar issue I had. You might want to do some more searching.I'm sure this kinda thing has been covered before. Anyways Check to make sure the sensor is in properly, sometimes it can become loose. I also remember I had to replace both cam sensors and the crank sensor before my z ran smoothly again. Another member will probably chime in on this...
