I am sure this issue has been beat to death multiple times, but I cant find the answer.
I have a 2005 Silverado 1500 z71, I have had this issue for about 2 years now. the issue being that no matter what part I replace my 4wd wont reliably work.
here is a list of what parts have been replaced.
Drivers side wheel hub- twice
Passenger Side wheel hub- three times
Diff. actuator- twice
4 button switch on dash- once
Transfer case motor- once
So what is happening is, the dash will read service 4wd, i have taken it in to a shop where they have been replacing the parts, and i have come to the conclusion they are just throwing parts at it to find a fix. Every time they would replace a part it will work about 2-3 days but then give me the same service 4wd message. if i push one of the 3 4wd buttons on the switch the light will blink for a while then stop and it seems like it doesn't shift into 4wd. But i have crawled under the truck while someone else selects a 4wd button, I can hear and feel the transfer case changing into to 4wd mode. but the front diff actuator does not engage. I have checked and cleaned the ground wire under the drivers door twice but that doesn't seem to help. I am done throwing money at the shop to fix it, so this is my last resort.
any help or ideas is greatly appreciated,
Had a 2018 Sierra 2500 for a loaner while my 1500 was having warranty work done. We got a couple 0 degree days here in St Louis during the polar vortex and the 2500 went into limp mode and wouldn't allow me to go above 25 mph. CEL came on and a message popped up "Reduced Engine Power". I was 30 miles from the dealer that loaned it to me and they sent someone out and gave me a 2019 Silverado 1500. Next day they towed the 2500 back and found the diesel fuel had "gelled" from the cold temps.
Curious, is this common in diesels? I let it warm up for at least 5 minutes before driving as I know diesels need a little more warm up time than gas engines. How could it idle and drive up to 25 mph with the fuel "gelled" as the dealer put it? Didn't shake or sputter, just had the rpm limiter kick in at 25 mph.
Hi, need help please. Hit black ice in my 03 Sierra 2500 with a duramax engine. Went over a 15 foot embankment and came down hard under front driver side corner which pushed everything up several inches. The motor was running when I shut it down but now will not start. I was thinking maybe an emergency fuel shut off was triggered but now i'm thinking maybe something else. Any ideas or help would be truly appreciated.
PS: jumping them isn't as fun as it looks on tv!

So I’ve just bought this truck, and when I try to start it the starter will sometimes stay on after the Motor fires for a few seconds. Then it has a very uneven idle. THEN when I rev the engine it wil rev up then drop down below normal idel and almost stall. This will go away if the truck is warm. Now the only thing I have done since getting it is to pull the pipe off of the purge valve next to the fuel tank because it is broken. I’ve ordered a new purge valve and will install it as soon as it gets in. Is it possible that this is causing some sort of low fuel pressure or something?
Has anyone else has issues like this?
