i tried starting my 03 350z today and it had trouble starting, when i finally got it able to start the SeS TCS and SLIP lights came on. i did a little research and it said it could be the crank sensor. just posting to see if thats true or is there another cause of it? ive owned the car for a year and no problems and all of a sudden this happens.

 

Do a full scan to pull codes and confirm the diagnosis. At least it's better than polling here and taking guesses.
