Thanks Mike, I'll see if I can try your suggestion.

I found this Tech Bulletin about the LBZ glowplugs. It is looking like at a minimum I will need to replace all 8 glow plugs. Someone told me that they cost around $33 to $40 Each. So that will be $264 to $320 for parts alone. If GM does the work it will probably be at least double that. If...

I swear, I must be going senile 'cause I can't find that DTC List on this forum. :???: I did a Google search and found the code on the diesel Garage posted by ripmf666. DTC DTC Descriptor Module That Sets the DTC Diagnostic Procedure P0677 - Glow Plug 7 Control Circuit Set by ECM --...

You are absolutely correct Mike, I just checked it again and it is P0677. - The Glow Light will NOT go out unless I start the engine and the CEL is ON solid. I'm so stressed out right now, I can hardly see straight. I have to get this bid done by tomorrow afternoon and this problem with the...

Can someone please, tell me what DTC P0667 means? These last two years have been financially devastating for us. Fortunately, I still have an excellent credit rating, so I've been able to borrow to stay afloat. Today, I am 120 miles from home trying to bid on a job and I certainly don't need...

We ended up getting the transmission rebuilt. Found that the reverse clutches were fried and one of the ring gears was damaged too. Had them replace everything that didn't look good and $2100 later the tranny is working again. The guy that rebuilt it gave us a 2yr/unlimited mileage warranty. I...

Sure is looking that way. Biggest problem right now is that the '06 is my every day driver. Couldn't afford to keep the other car. I'm reluctant to spend several hundred dollars to fit the '06 for the plow this late in the season. Plus, I would have to get something else to drive. So far we've...

This damned plow truck is JINXED! :banghead: Some how the power to the TLA is very erratic and weak. On the test bench, the TLA worked fine with a strong force, but plugging it to the harness on the truck it is very weak and mushy, so he ended up hot-wiring the TLA directly to the battery and...

Yes, it is strictly a plow/work truck. We just spent $2,100 to have the transmission rebuilt after it blew reverse while plowing and another $500 in repairs to the plow. Also had to replace the radiator that for some reason blew out the drain cock while on the expressway, blowing coolant all...

Well, the problem definitely IS the TLA. Pulled it out, and made sure the electrical connection is good and it seems to be working right now. It is warming up when electrical power is applied and at least on the hoist the 4WD is working. Hopefully it will keep working tonight so we can go out...

Is this the OEM part? http://cgi.ebay.com/ebaymotors/88-96-Chevy-Truck-Suburban-4x4-Front-Axle-Actuator-/370484726258?pt=Motors_Car_Truck_Parts_Accessories&fits=Make%3AGMC&hash=item56429c49f2

I found this on eBay. http://cgi.ebay.com/ebaymotors/4WD-4X4-Front-Actuator-Upgrade-w-WIRE-HARNESS-88959465-/230588064485?pt=Motors_Car_Truck_Parts_Accessories&fits=Make%3AGMC&hash=item35b01ea2e5 Is this what you are talking about? Will this work on a 1991 GMC 2500? Is there some place...

AK DD, thanks for your assistance. How difficult is it to replace this actuator? Is it very expensive? Is it possible that I may have a broken electrical connection somewhere? It is weird that it worked one minute, but after re-starting the engine, now it doesn't work. Is there some way to...

1991 GMC 2500 V8 4WD - Front axle quit working. Only rear wheels are driving now regardless of being shifted in 4-Hi or 4-Lo. Every thing worked fine until a few minutes ago when engine was shut down. Now after re-start, only rear wheels are driving. This is my son's plow truck and he need it...

Thank you all. I really appreciate the help. This really took me by surprise, because this truck has been pretty much trouble free since I bought it new. The only significant issue I've had was a bad ABS sensor that the dealer replaced on the very last day that my extended warranty was in...

Thanks for the info guys. I really appreciate it. I will have to go to the parts store and get some of that Mass Air Flow sensor cleaner. Do you take the sensor off to clean it? Do you just spray the cleaner on, or do you wipe if off also? Thanks. Since fund have been very tight for quite...

Does the MAF Sensor in a 2006 LBZ require periodic maintenance? If so, how often and what is the procedure? This morning during rush hour, I had to merge into traffic and I was required to push it WOT up to 55 mph in order to merge safely. Approx 2 miles down the road I had to stop and make a...

I am curious about this too. My son's '91 GMC 2500 gasser is doing the same exact thing. Slips like hell in reverse when in 2WD or 4WD Hi, but if he shifts the T-case into 4-Low it backs up fine. :WTF: This is his work plow truck and without reverse he is out of business. :sick:

No, there was no sign of any bearing problem, no steering pull or nothing. Other than that felt clunk while stopping and one of the steering wheel button lights that had gone out (They repaired that too under the extended warranty) the truck has been otherwise flawless. I am really picky about...

I've wondered the same thing and I was hoping to talk with the technician who worked on it. But by the time they called me to tell me the truck was done I had no way to get to the dealer, so I had to wait for their courtesy car to pick me up. When I finally got back to the dealer everyone was...
