I went to go pickup the 97 Yukon I’m supposed to be buying, for an engine swap, and it wouldn’t start. When I went to look originally, it fired right up and ran smooth as silk. Today it just cranked and cranked. When it did fire it sounded like the timing was way off. It was sitting since we looked at it on Monday. It was raining today where it was sunny and dry that day. I was thinking maybe a jumped timing chain but how is that even possible when the truck was not even driven?
