i am brand new on this forum and it seems i have found the right place to solve my problem because several gmc dealers cannot. i will try not to be too wordy but sometimes information is knowledge and a full detailed description of the problems may help in getting an answer.
a couple of weeks ago we were on a road trip to and around the grand canyon. I was pulling a 2003 cardinal 29WB with my 2002 2500HD D/A. (7900 miles on it) The loaded trailer came in at 10,800# This was our third road trip with this setup having previously done 1,000 mile yosemite and 2,000 mile yellowstone journeys without incident. On a short leg of the trip from Page, AZ to Flagstaff(200 miles) I noted the engine fan running about 80% of the time. The gas gauge barely moved the entire 200 miles down to like 3/4 tank. As we got close to Flagstaff, shifting became erratic with noticeable loss of power and normal punch. We got into CG in Flagstaff, registered, and pulled into site and the engine would not turn off. All of the gauges and dash lights went dark but the engine continued to run with maybe a bit of an increase in rpms. We let our fingers do the walkin' and located GMC dealer in Flagstaff. Went to leave the CG after dumping 5er and found the gear shift selector would only go to "N" position, but truck went into gear. Problem is it was 4th or 5th gear. Limped into dealership and they used hand held computer plugged into truck to shut it off. They had it 2 days and released it saying they put a bunch of upgrades into computer and all is now well. We left the dealership and drove 75 miles( without 5er) to south rim. got to first overlook and turned the key and truck kept running. Back to the dealership. 4 days later they released it after replacing the ECM and ignition switch and updating the new ECM. They felt all of the problems were interelated to the fried ECM. Headed for home Flagstaff to REno with an overnight in Pahrump,NV. got into vegas (about 240 miles) for fuel and lunch. all worked well. engine turned off twice. Towed 60 miles to Pahrump, checked in at CG , pulled into site and engine would not turn off. When the smoke cleared that had poured out of our ears, we called GM roadside assist. and customer service. (That nightmare could be another post) They sent us to dealer in Las Vegas. Unhooked the trailer, drove the 60 miles, pulled into the dealership and the sucker turned off. Service adviser basically said to bring it back when it's broken. They did show me location of fuel pump relay should it happen again when we got back to Pahrump. In the AM we left Pahrump to return home to Reno. Shortly after starting off the SES light came on. We drove home. Made appt. for all of these problems with our selling dealer. They had it 5 days. They never addressed anything but the SES light which was the heater intake relay. The service writer would not list the engine not turning off, gas gauge, engine fan running constantly on the work order because they were not manifesting themselves then. A FRANK discussion with the service manager ensued and he backed the writer up. But I stray from the problem. The engine turns off all the time now, the gas gauge seems okay and the engine cooling fan has calmed down. I don't know if these things fix themselves;I rather doubt it. My concern is the next road trip we take and we stop in XXXXX, Colorado and there will not be a GMC dealer within 300 miles. Anybody have suggestions? Anybody experienced failure of engine to turn off?
