Hey guys, been awhile but honestly, my lbz has been the most reliable truck I've owned. On my way back from a thanksgiving week camping/atv trip to Fat Daddys ATV park outside of Waycross, GA (about 2 hr. 20 min trip), towing my 21 foot enclosed toy hauler at capacity (7k), the passenger side battery took a dump. Noticed a slow start after after filling the tank in Waycross before we headed back. The first thing I noticed was my fuel gauge was way above full, which is not normal, then, several miles down the road she thru a p0116 (engine coolant temperature range/performance problem) and immediately went into (what I think was) limp mode it was skipping and vibrating slightly and it's been so long since she's been in limp mode I don't remember if it studdered like that before. I checked the temps via app and OBD port, everything was normal. Left my tablet on the console and rocked on home, clearing the codes a couple of times. It would seem to only throw the code during the first 10 minutes of driving, once up to temp, no code. And it didn't matter if I was cruising down the interstate or start and stop through small towns. My batteries were almost 5 years old and I've been trying to replace them but interstate has been having trouble getting blems. So, I took the trip knowing that my batteries could be an issue. Called interstate a few days after we got back and they had blems in stock. Installed the new batteries and I have not had that code come up again until yesterday on my way home from work, again before she got up to operating temps. I cleared the code and it came right back, like in 2-3 seconds. At about the halfway point of my 13 mile commute it went in to limp mode again, this time I had a different code, p2155 (fuel injector group D supply voltage circuit/open). It's kidding season on the farm and I have goat kids coming out of my ears so I didn't have time to mess with it last night. This morning, I looked everything over to make sure there were no obvious issues like fuel/air leaks, chaffed wires etc. Embarrassing as it is, back when I had to replace the TCM, I thoroughly cleaned the grounds under the driver door on the frame. Backing up here, I tested the 4wd a week before our trip and it did not work and i had the service 4wd message on the DIC. I worked on that issue for three days before finally checking youtube and only one video of many, the first thing they suggested to test was the grounds, always test the grounds. Well, knowing that I had just thoroughly cleaned the grounds last year, I was like "yeah, whatever, it's not my grounds"...only to decide to just check them. I looked up and I only had one nice, clean, sealed ground...I thought, hmm, I believe there were two grounds under that bolt. Sure nuff, I had flipped one of them over the body mount brace while cleaning them and forgot to pull it back down and connect it while I was troubleshooting my TCM issue. Reconnected that ground and 4wd worked perfectly. I share all of that just to say the grounds are good lol. So, this morning, I did a little more checking including looking for pressed in pins on the connectors to and from the ECM. Started the truck and she purrs like a kitten. I let it idle for about 5 minutes occasionally increasing the rpms. I should also add, I think I need to replace the thermostats again as it does not get to full operating temps when unloaded only when pulling a trailer. They would get to about 185 during the summer empty. I have not road tested it yet and wanted to hop on here to pick the minds of the best in the field!
Thanks guys, Hope you all had a great Christmas and are managing to survive this horrible economy.
