#1 of 10 2000 GMC Yukon Denali Computer Problems by steelrz May 08, 2007 (7:15 am)
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 !!!

Replying to: tidester (May 08, 2007 9:52 am) They thought it was fried, but then it responded to them when they accessed it at the dealer so the dealer put a new program on it and it worked, at least for a day, then it died again. Replies to this message: rsht (May 22, 2007 4:58 am)

Replying to: steelrz (May 08, 2007 10:01 am) I had a 2000 Chevy conversion van that had the exact same problem as you have described. At the time, my dealership also just re-programmed its on-board computer initially; but, I was lucky, my ex-van's engine quit before I even drove it out of the service lot. The entire computer was then replaced and the problem was solved...

Replying to: steelrz (May 08, 2007 7:15 am) I am now having the exact same problem as you with my 2000 GMC Yukon Denali. What is the status on yours?

My 96 Yukon whle driving will show erratic tach and speedo and then they will stop working. transmission shifts hard, check engine soon light comes on, gear indicator goes off. Computer codes are transmission codes I'm told. A restart clears tach and speedo, transmission takes a little while to recover. Mechanic thinks bad connection but hasn't found it. Any ideas are welcome.

The problem with my 96 yukon mentioned above turned out to be in the ignition switch. $500 and all is well, I think

Replying to: steelrz (May 08, 2007 7:15 am) Sounds like a distributor. I have a 1995 2 dr Tahoe and it stopped all of a sudden on me like that. I waited 15 minutes and it started back up. But, it just got worse and worse...then i took it to a shop and it was the distributor (about 400 bucks). Knowing things changed from 1995 to late 90's on those things, it could be something else. Computer problems don't sound promising...and that could be because the dealership you took it to may have been a small one with little-skilled mechanics or just did a temporary fix. I would say either take it to a major gmc/chevy dealership or see if it starts after an hour or so. It could very well start again and then you know it's the distributor. Hopefully this info will help you in some way.

Replying to: marccristy (Aug 08, 2009 9:47 pm) The first things to check would be the wiring and fuse.   tidester, host SUVs and Smart Shopper
