  1. 98.5-02 Powertrain
    I have a 2001 6 speed manual 2500 with a dead pedal/runaway throttle, it changes randomly and sometimes will almost redline without me touching the pedal. It will drive normal for a few minutes then start doing this every time. At first I thought it was the TPS but I have put 2 different ones in...
  2. 3rd Gen. Non-Powertrain
    I purchased an 06 5.9 not running (got it cheap, rust free, and stock) , would crank all day but wouldn't start and kept blowing the #42 fuse which is for the ECM. I ordered an ECM from ACE.com and installed it. Truck fired right up! I got excited but Tach and oil pressure gauge do not work...
  3. 07.5 - 09 3rd Gen 6.7L Non-Powertrain
    Im lost! I own a 2007.5 6.7. Ive had it for about 4 years. Some days are great some days not so much! When I first got the truck on the drive home the truck began to accelerate on its own. I had to throw the truck into Neutral and turn the truck off once I was at a slow enough speed. I then...
  4. 3rd Gen. Non-Powertrain
    Just switched motors in my 2003 5.9. The motor came out of an 03 as well and we got everything together and motor turns over but won’t stay running. Got a code that said mismatched vehicle identification number. Got it put on a wrecker and took it to the dealership and they replaced the...
  5. 2013-2018 Powertrain
    need some help, got a 2015 6.7. Put in a EZ lynk tuner 150hp about a year ago. No problems. Took it to the dealer to get warranty to cover wheel bearing. Got the truck back and when I’m on the freeway 6th revs up twice maybe three times and goes. Yesterday I got a couple lights for it, asked my...
  6. 98.5-02 Non-Powertrain
    Hey guys, a couple of weeks ago I had a bad fuel leak out of my fuel heater on the top of my fuel filter housing. I installed a block off plug from genos garage to fix the issue. After installing the block off plug, I tried to prime the truck and upon turning the truck on, I had to wait to start...

  9. 5th Gen Powertrain
    Just wondering if anyone has run into the same problem? If so how did you resolve it? Dealership wants $2200 to drop in new ECM. I attempted to flash in new tunes the other day, the upload failed at like 94%. It seems to have completely scrambled the ecm, it will not take or send any...

  11. 3rd Gen. Non-Powertrain
    I have an open wire somewhere between the number 7 pin of the data link connector and pin 16 of a connector on the ECM. I have gotten this far and currently stumped, cant see a broken wire and not sure exactly where the harness runs. Also not sure what the breaks are on the wiring diagram. Any...
