GMC Yukon died suddenly and didn't start back up
My 2002 GMC Yukon died all of a sudden today when I was backing out of a parking spot. There were no odd noises, no sputtering, no rough or high idle, no smells or leaks, no CE or other lights. Literally no sign that I can think of that would make me think anything was wrong with it. When I tried to start it back up the engine would turn over but not completely engage. I ended up having it towed. It has 150,000 miles on it but seemed to run just fine. Ave it's not the XL package. Abby ideas where I should start looking to figure out what's wrong?
