First off, hello every one. New to the forum, but have been searching different posts for a while trying to pinpoint a problem with my 08 Grand Prix GXP. From what I've read, I think my problem is the Crank Position Sensor. Similar problems with the car randomly shutting off while displaying the TC and ABS lights, ect. Also, just not starting for no appearant reason. Had the battery and alternator checked, and both came back good. So, can anyone tell me where the CPS is located and how to remove it. I saw a write up on the removal of one, but it was for a supercharged GTP. Any help would be greatly appreciated. Thanks, Brian
