Ive slowly been bringing 2003 Denali 6.0 back into maintenance... replaced a few parts without issues but after a water pump install the truck will now turn over but not crank. Had mech with scanner come out no codes shown to prevent start or run. Was running before the water pump install without issue other than small leak from water pump. Fuel system test fine, timing is true, spark is present, battery is brand new (figure might as well get one to be on safe side) , has almost full tank of gas, MAF has been cleaned. A new throttle body sensor, thermostat, radiator installed two weeks before water pump install..no issues at that time or after till the water pump started a leak from pressure change after new radiator. As of right now its sitting in the garage with the battery out to kill the entire system to see if a reset will do anything...while I sit here baffled as to what the issue may be.

Ok, We are all familiar with the instrument cluster (servo) issues with the early 2000's trucks... I have the same story. gauges started to fail one at a time. For the last several years, all I had working was the fuel gauge. (I would measure speed by my GPS, and I have an OBDII module where I could read oil pressure, coolant, anything else...) Anyway, I drove my wife's vehicle to work for a night because she was loading some stuff to take elsewhere. When I got in my truck the next night, I noticed she had moved the steering wheel up. I moved it back down to my preferred position, and when I started the truck, ALL my gauges worked... I even had lights lit that had been out for years... But the REALLY odd thing, is my odometer now shows ~ 80k less miles than it did last week... I was under the belief that the mileage was in the "computer", not the dashboard... and my wife never even started the truck, only loaded some things in to it.... Anyone have any thoughts?

I have a 2003 yukon sle 2wd. The radio, windows, gauges on right side of the dash all stop working. The abs, tc and air bag lights come on. Now if you press the brake the radio and windows work. The gauges sometime come back on. The vehicle runs good now stalling issues or anything. Just wondering if anyone has any ideas what could cause this.

I have a 2003 Chevy 2500hd 6.6l diesel. All gears and shifting were working fine. Pulled out on highway today and had to get on it. When going through gears I heard it slip up and rev as if it slipped out of gear. I slowed down and got off road. It seemed to be stuck in 3rd gear. I tried putting it into reverse and it would not work. The shifter doesn’t even feel like it’s moving into gear when I move into reverse. When I move shifter to Drive, it sounds very rough and it starts off in 3rd gear. The truck will not shift out of this stuck gear, not even go into reverse. Had to put home slowly in that gear range. Need some help, What’s going on?

I have a 2003 Yukon XL 2500. The radio started to cut in and out, and then soon gets to the point where there is no audio at all. No chimes and no radio. However the rear radio headphones still work. Thus I thought this was the bose amp and changed the amp. The new amp made no difference until I pulled both fuses and checked everything. I put the fuses back in and I had sound. Great. 2 hours later on the new amp the radio started to cut out again and then I had no sound. No chimes, no radio. I can restore the radio sound by pulling the radio fuse for 5 minutes, plugging it back in and all audio is restored. This does not last long and soon I will be back to no audio at all. It is not the amp as a brand new amp does the exact same thing. So how do I figure out what is wrong? I don't want to start replacing things as that did not go well with the amp. I have read that maybe there is a bad speaker, but since the speakers plug into the amp a bad speaker should only impact the amp. Also since the audio starts to cut in and out many times (longer each time) until there is no audio at all I can't imagine a bad speaker causing that. Once the speaker is detected it should cut the audio off until reset. Only pulling the radio fuse, waiting and then putting it back, will restore the audio. Is the radio bad? I pulled the codes and there seems to be nothing for the radio once the audio is lost. Thanks for any help!

I am replacing the bench seat in my 86 K10 to a 40/20/40 seat set. The driver side seat is electric adjustment only, not heated. Is there more to wiring the seat up other than running a new power & ground wire from the fuse panel?

So some of you are probably aware I had a little "incident" requiring me to replace both hood lift spring hinges and the hood hinge supports on both sides. I'm just wondering what order you would assemble it to prevent any further headaches or injury. So far I've marked with a sharpie where the hood hinge supports attach to my hood (three bolts each side) so it'll line up near where it belongs. I was planning on removing the one bolt and nut on each side of the hood near the windshield cowl that holds the hood to the truck. Then having a neighbor help me lift off the hood I will flip it over and install my new hood hinge supports (three bolts each side) I'm wondering should I wait until the hood hinge supports and hood itself are installed before installing the hood hinge that contains the spring (and lifts the hood) on each side? Or when the hood is off should I install the hood spring hinges? My theory would be it might be easier to install the hood without the hood spring assemblies installed yet so it could sit flat instead of in a lifted position. But I very well could be wrong The other option would be to install the hood spring assembly on each side while the hood is off (but would require my helper and I to lift the hood on in a raised position, then attach the hood hinges with the springs to the hood hinge supports in a "hood raised" position. I want to prevent a mistake or any major problem from doing this incorrectly. Also do you know if the hood hinges with the springs attach with the bolt side in or the nut side in? If anyone has access to information that says how this is supposed to be done and would share an image it would be greatly appreciated. If not, what order would you go about doing this? Hood hinge supports first (with the one bolt on each cowl side going in first, then lift hood to install spring assemblies, or install spring assemblies whole the hood is off or do I have this all wrong. Hopefully I made sense out of this because the parts come tomorrow. Thanks very much.

Im swapping a 4.3 out of a silverado 2003 into a 1996 silverado trans is 4l60 e. Out of a 1998 jimmy they changed transmission to ls style for. 2003 4.3. Do they sell adapters for this. Or a special torque converter. Can I just use the ls to 4l60e adapter with new bell housing if I swap trans to 2003 it moves everything back 3/4 of an inch do I have to modify drive shaft trans mount
