I have a 2003 Z71 Suburban that has similar issues. In fact it is at the dealer now and they are able to replicate the problem. The first thought was replace the fuel pump. So, we tried that and after the 4th fuel pump they decided that must not be the problem! The dealer has had no luck and has had it for five days now. They will be calling GM in the morning to see if someone can come up with an answer.
As stated above our experiences seem to be similar in that we are unable to start the Suburban in the mornings when the vehicle has sat for several hours. Then once started after several attempts it dies when traveling down the road. I also noticed that it started accelerating in a school zone from 20 mph to 25 mph in a matter of 50 - 75 yards without pressing the accelerator.
We just put in a new battery two weeks ago and just did our 60K service at the dealer.
I will post again after we find a solution.
#374 of 1043 traction off / ABS lights are on
Sep 26, 2005 (6:59 pm)
I have an 01' LT 2WD burb with 60,0000 miles on it epuipped with traction control. Recently, the "traction off and the ABS" lights came on at the same time and stay on all the time. Has anyone else had this problem. Is it anything I can fix by buying parts at the local auto parts store or is it one of those dealer only items.

ABS and traction systems both use wheel speed sensors. ABS for wheel lock-up during braking and traction control for wheel spin during acceleration.
If a sensor that both systems use goes bad you'll get warning light for both systems.
First check sensors that they have not been knocked off correct alignment to the signal sending wheels that they read. The end of a sensor normally is mounted really close to the wheel it reads. I have not looked at the sensors in my Tahoe but an old Ford I used to have had only about 0.030" gap between the sensor and the sending wheel.
Check the wiring, especially the wire harness. Sometimes moisture penetrates inside harness and corrodes the contact pins.
If wires, harness and sensor alignments are ok BUY ONE SENSOR and rotate it in each wheel to see if you find a bad one. I don't know how much a sensor cost but to take your car to a dealer or anybody else for diagnostic will cost you $70 - $80, which easily is more than the sensor cost. For example the crank shaft position sensor that I believe works exactly the same way as wheel speed sensor cost $63 + tax.
I'm not sure if ABS and traction system warnings set a code in your car's computer but to check for that can be done for free at AutoZone and perhaps in other car part stores. If there is a code it probably says what sensor is bad if it is a sensor problem.
Usually wheel speed sensors are easy to change so little work can save you few hundred dollars.
I'm talking about the wheel speed sensors here because I don't know any other parts that ABS and traction systems have in common. This does not mean that there isn't any though.
As today's cars all have a lot of sensors to go bad I recommend to purchase a scanner that reads and resets computer codes. I bought an OBD II scanner years ago for my Ford as all cars have connection for it since 1997 I believe. Scanner has saved me its cost many times over as it only cost about $100.

Sep 29, 2005 (8:39 am)
I just got my 99 back form the trany shop. Check to see what transfer case you have. There is a silver dollar sized tag on the back side of the case half. It is probably a NP246. What is happening is this transfer case has a oil pump in the rear case half. The flange on the pump rides on a little steel shim inside the case and it eventuly wears out and the flange rubs a hole in to the case causing the leak. From the outside it looks like a casting mark or hole but it is caused from the inside. You can try to plug the hole and this will buy you some time. But it will ware additional holes in the case half. The problem that I found is that this seems to be a fairly widespread problem. The trany shop could not get a replacement case half from his suppliers and they have been on back order since June. We had to get a case half from GM ($200.00 more than the aftermarket case, Identical part numbers) Bottom line is $860 to replace case half. But, no more leak.

What about the thermo stat? If you did all that, do that too. Any coolant in the oil? If so, the engine has a cracked gasket.

My old 89 Suburban 454cc had 220k on the clock and a compression check said it was 100% on all eight when I sold it! The question is how much $$ will you put into it to get another 150k out of her. I would do a compression check to confirm how much $$

www.radiatorbarn.com has great prices! Try this, disconnect the hose that goes into the radiator after the thermo stat. Then pop off the radiator cap and put your garden hose in there on medium pressure. Start it up. Does the hose that connects to the thermo stat and radiator have coolant coming out? If not, thermo stat is bad or a blocked radiator
#381 of 1043 Need Electrical Help Please.
Oct 03, 2005 (12:16 pm)
Ok here's the scoop. I unknowingly plugged in a faulty trailer wiring harness into my 1997 suburban wiring plug. The harness felt like it was getting hot so I immediately unplugged the harness. I found a blown fuse in the box under the hood and replaced it figuring no damage done. Well this apparently is not the case. My brake lights no longer work and my hazard lights are intermittent. I have checked every fuse and the bulbs and everything is good. No other lights headlights/taillights, turn signals etc... are affected. Also the center brake light above the rear doors is working fine just the left and right brake lights are not working. Any help or insight will be greatly appreciated!!!

I don't know much about vehicles and could use some advice at 1986 Chevy Suburban Diesel I'm looking at (because I want to convert it to run on vegetable oil - www.vegenergy.com).
The one I'm looking at has 200,000 miles, a rebuit transmisstion and transfer case. A/C and power steering.
How many miles have well mainained Suburban's been known run for?
What is a reasonal price to pay for this vehicle?
