My son just joined the Army and he left his 2003 Sierra 2500 Duramax truck with us. He wants us to sell the truck for him. However, it needs a few things done before that can happen. One thing is resetting the computer to stock for smog testing (California's new law). He has a Duramax engine analyzer that can accomplish the task but there seems to be no power at the plug under the dash. I spoke to him briefly last night and he suggested checking the fuse. I can't seem to decipher the owner's manual to find the correct one? The chart in the manual does not specify which fuse might be connected to this outlet.
I checked all of the ignition fuses and they were all fine.
Any ideas would be appreciated.
PS - He has installed and removed several stereos so there could be a connection, no pun intended, with these activities. Thanks in advance.

Checked all fuses, changed 3 relays, new ignition, did load test on batteries and a few other things. does not throw codes. Oh and when it shuts down and you try to re start you will get the radio and dash lights but the fuel gage does not register. That is on the first click when you try to turn it over from there everything goes off. It loses all power and will not even thing of turning over. I am guessing electrical or something... Please help!
I apologize that you are experiencing a concern with your vehicle. Can you please email me your VIN and current mileage so I can look into this further? You can get my email by clicking on gmcustsvc. Thank you,

I have a duramax 2003 automatic.. it is doing the same thing... shifting out of gear and showing "range shift inhibited" on the display.. 2 dealerships have not figured it out.. I am so frustrated.. all they want to do is drive my truck and see if it does it again! I don't have time for them to keep my truck and drive it around! I am taking your post to the dealership! did you get your issue resolved?
thanks
Jarrett
Give it a quick sharp snap and it will break free.
Good luck
Also it seems to me that most people I talk to about fuel mileage seem to stretch it a bit(maybe trying to justify paying the extra for the diesel). I say this because some that I have talked to that claim far better mileage than I get, when we go on trips pulling similar loads when we do stop for fuel we are within 1 or 2 gallons of each other in fuel used, they should have used far less than I did since they get much better mileage. I don't know maybe it's the new math.
One ton truck with pulling power and respectable fuel mileage is a lot better than FORDS same if not worse mileage, if you can get out of your rental car enough to drive it or the earlier 6.0 they had in 04, where you kept looking for the "power" switch.
I get 14 mpg city in my 08(programmed to 500 hp) and about 22 hwy. My last 05 got 18 city & 24 hwy. Like the new one better, and I can make a 5L GT mustang look stupid!
The 8th digit in your v.i.n. tells you if you have the fuel saving #2" LLY #D"LBZ if it's a 6
it is the same as mine LMM 390 H.P. A LITTLE TOUGH ON FUEL,BUT THE BEST TRUCK ON THE ROAD!
but my last trip,I kept it under 70mph the whole time and got less than 17mpg. The truck is stock from the day I bought it brand new. I would expect worse mileage when I have my tools in the truck,but this trip the truck was empty. If I wentv with a chip,what kind of problems or damage to my truck should I expect? anybody?
Have you resolved the issues with your vehicle?

GMC only wants to pay half to get my truck fixed. It will still cost me 2k-2.5K to get fixed!!! The truck only has 80K on it, GMC should pick up all the cost!!! I don't have 2K to fix the truck right now! This sucks!!!!!!
Can you get me Dan Downings phone #? I would like to talk to him, my so called district specialist Jerrod at ext. 11060 is not so helpfull!!!
Aaron
My advice would be not to buy the Duramax unless you want to change out your head gaskets at 80K miles! If you do buy get the extended waranty!!! Diesels are very expensive to fix!!!! Replace head gaskets 3.5K-4.5K to fix!
As you can tell I'm not to happy with GMC right now! It is the end of February I have been dealing with this since the 1st of the year. It's been 2 months and I am finally suppose to ge my truck back today!!!!
Good luck!!!!!
I would not add a thing to the motor or exhaust, for warranty reasons but also because it simply does not need it.
I love this truck I have just over 60,000 miles and no problems.
Please keep me updated on your situation.

Got my truck back 2 weeks ago from the dealer (after they pulled the heads and sent them off to the machine shop and put it all back together). Drove it 10 miles to my work from the dealer and when I got to my work coolant was spewing all over the place. Had a flat bed truck come pick my truck up, couple of days later dealer calls me back saying it needs a new cylinder head. Waited a week for new cylinder head, dealer starts putting engine back together and calls me and says it needs new exaust valves in a couple of cylinders. Was told last week that I should get my truck back this week. I have been dealing with this since the end of December. The truck barely has 80k miles on it. The duramax diesel engine is a piece of crap!!!!!!!!!!!!!!!

My truck is an O3. I loved this truck before all the problems. The 80K miles I have on it are all long distance road miles on weekend trips. It's a good lookin truck. It's sits with a cover on it in my driveway during the week. I was told when I bought this truck that the engine would break in at 100K. Very disapointed with this truck.
You might want to check out getting extended waranty, if you have to do any major work to the engine it is very expensive. Blown head gasket on the duramax is a 34 hour job at $100 per hour, you know what I'm saying! Thats just labor, parts are another 12 to 15 hundred bucks.
I am lucky, I have a beater that I drive for work, If I did'nt, wonder how much a rental car would have been. Truck has been down now for 2.5 months at 40.00 per day = Doh!!!!!!!!
Duramax = FAIL!!!!!!!
'yet'. Wonder if a chip would be an option for better mileage and power at this point.
I don't have the readout computer, but I keep exact "per mile", "per tank" records. I get 9-10MPG with 12k trailer, 17-18MPH solo around town.
Anyone had any experience with the new 2011 "DEF" system? Reluctant to buy it.
