    I have a 2006 Silverado 6.0L. I recently installed a Mpc remote start kit on it. On of the plugs came lose while driving and threw a abs light and brake light. About 20 miles later the check engine light came on. I checked the codes and I got c0035, c0040, u1041 and p0332. I reset the codes and...
  2. 6.2L Diesel Engine
    I have so much corrosion on my big plug do I need to get in there with a brush or just use dielectric grease. Maybe a pipe cleaner on a drill....thanks
  3. 6.5L Diesel Engine
    I wanted to run my truck today for a bit. so I got in the truck and when I turned the key I got extremely low power to the warning lights and to the radio and fan. the fan still blew and the cab lights acted fine. just low power to the warning lights in the dash and to the other electrical stuff...
  4. 6.5L Diesel Engine
    Hi guys, the last 3 mornings I've tried to start the truck and I won't get a wait to start light when the key is turned. The controller is not energizing and my lift pump which is wired into the glow plugs doesn't start up. If I try and start it the truck turns over no problem but won't...
  5. 6.5L Diesel Engine
    New guy with a recently acquired 1996 Sierra K3500 and I don't know enough about the wiring relationships and thought a diagram could help. Problem #1: I removed the cluster and sent it off to be repaired as nearly all the gauges were flat lying to me. The aftermath is that the batts won't...
  6. 6.5L Diesel Engine
    The leads of one of the 2 batteries were momentarily switched on my 1993 Silverado truck during maintenance. The cables were removed quickly (but not quick enough). No fuses were blown, when you turn on the key every thin comes on including glow plugs. As soon as you activate the starter you get...
  7. 6.5L Diesel Engine
    I have a 2001 Chevy c3500hd with a 12 foot flatbed and I seem to have a short to ground somewhere in the wiring. I recently replaced all of the rear lighting like reverse lights, tail lights, and marker lights with leds. I changed the flasher module to take care of the hyper flash, soldered all...
  8. 6.5L Diesel Engine
    Hi, everyone. Apologies if this is answered elsewhere, but I can't seem to find any precise answers. My turn signals and hazards were working intermittently; working the hazards button on and off repeatedly seemed to help. I replaced the multifunction switch, and now I have no turn signal or...

  10. Duramax First Generation: 2001-2004 (LB7)
    I have an 03 lb7 in a 94 k1500. I have been somewhat daily-ING this thing for a month. As of yesterday My EDU Relay is stuck on even with the key in the off position, causing the fpr to stay powered and in turn causing a huge power draw. I swapped with a known good relay and it does the same...

    Read a bunch of the no dash lights threads and didn't see my problem so figured I'd post. No dash lights unless I raise the rear driver's side window. Going down does nothing only on the up function. Other than that the dash lights don't work at all.
  12. Duramax Second Generation: 2004.5-2005 (LLY)
    I've been slowly getting my newly purchased LLY up to par. The fuel guage has never worked correctly and the previous owner said it had been out for a while. When I bought it the odometer read error yet the gear indicator worked. For 2 weeks of driving there wasn't anything weird happening...

    I purchased a 2018 Denali 3500 SRW on Friday. Drove it home to Florida from SC no issues. Hit the unlock button on keyfob yesterday morning to head to work, the doors started locking themselves over and over. I had to time the unlock button on fob while pulling door handle to even get in...
  16. Duramax Fourth Generation: 2007.5-2010 (LMM)
    07 Duramax LMM stop running after an hour road trip. Went to start the truck, but the engine will only crank over. I checked the fuel pump fuse and not getting power. I need some ideas of what sends power to that fuse to run the fuel pump.
  17. Medium Duty Trucks
    Hey gang, all of a sudden my tail light fuse is blowing when I hit a bump hard which is easy to do here in OK. I've checked all the connections on my lights and they all seem to be tight. Brake and turn signals are fine. Thoughts, suggestions??
  18. 6.5L Diesel Engine
    I searched as best I can but cannot find a similar thread. I recently had a the truck stop suddenly and would not restart. It would run about 1 second but nothing else. New PMD (SS Diesel) didn't solve issue. I replaced the fuel solenoid today and because I had to remove the plenum cover to...
