We need more information. Why did you do the CKPS?

We changed it cause the code popped up for it. The car started misfiring after driving it for awhile. So we replaced it and now it wont start at all. It used to start up fine before we changed it.

Yup or plug cam sensor shares the 12 volt power feed with the crank sensor so use a scan tool to see if you have a cam pulse, then check the 3x and 18x crank sensor pulses and see if both are there or not.. and buy oem acdelco parts, after market parts on these 3800's don't work well if at all
