Question about 1999 GMC Yukon
No its definitly not the cataletic convertor because it just a thing that convertors bad gasses to good gasses so when it comes out the exhaust its not to bad for the air, and dosnt cause as much pullution. you should check the battery if it is old, then needs to be replaced. if its really dirty then clean it the battery post so it has a good connection. or check if any cables are loose. if its not that then it could be your starter it not cranking.
