I have a 99 Yukon Denali and it recently had an engine code pop up. A local oil change place was able to get a code of P1416 on their scanner, but did not have the book to decode it. The next day, the light went off, but today the car won't start (it just clicks). After seeing the advice about the emissions check valve, can anyone say if "not starting" is a possible result of that issue, or should the car have just gone to limp mode? Thanks for any help.....Dan
