2000 GMC Yukon Denali Computer Problems
I have owned my 2000 GMC Yukon Denali for about 2 years now and have not had any issues with it. But Saturday as I was driving down the freeway at 65mph it just suddenly quit on me. I merged over to the shoulder and popped the hood, everything looked fine. I tried starting it again a few times and it cranked and cranked but would not fire up. I had it towed to a shop and the shop looked at it but they could not get their diagnostic tool to get any information from the computer. So they figured the computer was fried. They brought it to the dealer, the dealer reprogrammed the computer and it fired right up and worked fine. I then drove it for another day and a half before it did the same thing to me this morning. Does anyone have ANY idea why the computer would keep losing it's programming like this? Up until last Saturday this car fired right up and ran like a champ. HELP !!!
