both back tires came apart by swaney2
Oct 30, 2005 (9:03 am)
A couple of months ago i bought a 2002 gmc 2500hd and I really enjoy it. It has the 6.0 vortec engine in it. One day i decided to see what it had and powerbraked it and boy did it smoke the tires on it. I have had a lot of play toys before that I smoked tires with but when I did it in the truck the tires literally came apart. Why DO you think this happened?

VERY IMPORTANT!!! by 19gmc98
Oct 31, 2005 (11:01 pm)
I have a 1998 GMC SIERRA. With a 5.7L Vortec V-8. I have been having a problem with it not starting up as i turn the key. It cranks for a while and then when i let off and then turn it over again, it will fire off. Just recently it has got an even worse problem that i cannot figure out at all. It absolutly will not fire off at all when i turn the key over. The only way to get it to start is by taking the air box off the top of the throttle body and pouring a little bit of fuel down the throttle body, then when turing to key over it will start. Otherwise without pouring that fuel in it will not start. Then once it is started i can drive it for hours even hundreds of mile without any problems. but once it sits over night or more then a half hour, i must pour fuel into the throttle body to get it to start. And the injectors were brand new as of 8/30/05. This is a serious problem that i need to figure out and get fixed, and i am without a guess as to what it is. I would greatly appreciate it someone could help me. Thank you very much!!

It sounds to me like you have a partial fuel line blockage, most likely at the point where the fuel line meets the throttle body. If I were you I would have the mechanic who installed the new injectors check to see if he didn't accidentally cause the blockage. It should still be under warranty if the work was done at a reputable shop. It wouldn't hurt to check the fuel filter while you are at it.

If i had a partial fuel line blockage, would it run fine when it is started??? Because as soon as i get it started it runs fine, good power, doesnt run rough, or sputter. Do you think i may have a low fuel pressure issue??

I have the same problem... since I bought my 04 1500 .. i figured this was just the way it was factory... so I always put it on defrost. Have you found a solution?

GMC Professional Grade??? by fisherman2
Nov 07, 2005 (3:13 pm)
I have a 03 1500 Sierra SLE 4x2 purchased from local dealer.I have brought the truck there for all services since new.Last week when I brought truck in for regular oil change they told me I needed a Steering Shaft,and an inner tie rod.They gave me an estimate for 525.After going home and thinking about it I called GM and told them my issue.I have just hit 42,000 so was out of warranty.They called the dealership,and the dealership agreed to fix it for 100 under Goodwill Policy.
I am also having them fix another strange problem with this truck.When truck was about 2 weeks old,I pulled into driveway and when I closed the door I heard something hit the ground.It looked like a louvered 4x10 plastic filter.I took it back to dealer and inquired what exactly fell off my truck.Supposedly this baffle,or whatever you want to call it stops your windows from shattering if you close the doors too quickly.They ordered a new one and supposedly changed it.Every time we had a good downpour here I would have water laying in back of cab on side where this "baffle" fell out.I don't think they ever replaced it because it,because accroding to the dealer the bed had to be removed.Anyway they are going to fix this problem as well.
I've also had the tailgate adjusted 3x's,finally getting it right after the third time.For the money,GMC is not the Professional Grade it claims to be.I've had trucks for almost 20 years and after this is fixed,I'm trading it in and buying either a Toyota or Nissan.I know people like to keep buying American,but I've finally had it.They are built like crap,and don't hold their value.Just look at the interior of a GMC and then go look at a rice burner,there is a big difference in quality.
After a little over 2 years with this truck,i've lost my confidence in it.The engine seems great 5.3,but the rest of the truck will fall apart around the engine.

Your post only proves that GM/GMC quality hasn't changed for the better as they claim. GM has been fighting steering shaft problems since the first model year '99 NBS trucks. Get ready to lose your shirt and then some at trade-in time.

I know full well I'm going to take a beating on this.I paid 26 grand plus for this truck,plus a LEER cap.I know they are going to try an give me like 13 grand for it even though Edmunds and KBB have it at 15 grand +.I also just put a set on new tires on it 2 months ago.If I don't get 16 for it,no deal end of story.I've already begun my research on the Frontier and Tacoma.I'm pretty good at bargaining,I'll wait to the last day of the month etc to make a deal on this truck.

FRONT DISC BREATHER? by ssdpturner
Nov 08, 2005 (2:23 pm)
Anyone ever heard of a Front Disc Breather.....part of the differential and transfer case? This is off a 2000 1500 Sierra SLT 4WD. I had my transfer case serviced a while back due to a "leak" (see message 1095 dated 20 July). At this time they serviced the transfer case and replaced the seal. Anyways, I went out of town on business for an extended duration and I came home and seen a puddle under the truck. Took it back to the dealer and they tell me that the Front Disc Breather is bad causing the leak. They don't have the part on hand so they have to order it, but I am requesting they give me the bad part upon replacement. I am just curious if anyone ever heard of it. Could not find it in my Chilton's manual either. Kind of makes me wonder if that was the original problem the first time around.

My steering shaft went and had it changed last mont . Truck is less than a year old. Most of the problems these trucks have are common to the breed but you'll never get a dealer to admit it. Most of the time they'll play dumb like they aren't aware of a common problem.
