Hey guys/gals, I'm new to the forum (and Diesels/Duramax/Chevy's... etc).
I'll try to be as detailed as necessary without getting to far in the weeds.
So a couple of weeks I purchased a 2015 LML, Silverado LT. It had 48k miles and was very clean. I've noticed some small electrical "funny business", but nothing too off (Bluetooth would hold the phone connection even after the truck was turned off and I exited the vehicle. Now I've had vehicles my who life with BT issues, so I thought nothing of it.)
No codes have yet been appearing.
Yesterday (3/29), I installed an AirDog lift pump and GDP EZ Lynk tuner. I have not removed any emissions equipment. But lets backup half a step...
Upon near completion of the AirDog install, I thought I had found the fuse that would turn on when the key was a the "on" position, but not cranked. Not the case, had to go with another switch (I forgot right now which it was). In doing so, the computer started going a little crazy. I received 3+ codes on the screen calling out the trailer brake system, trailer lights, "Stabilitrack"... etc. Freaked me out. To make matters worse, when I did find a switch that would only turn on with the "On" position, primed the AirDog, the engine would only crank once and then not turn over. Again, multiple codes on the dash display. I
everywhere.
After calling AirDog (and the dude acting like a complete asshole at first as if I was blaming AirDog... was just looking for some help, but I understand), I resolved it was simply an electrical issue, and I needed some data to work with. Welp, I bought this fancy little EZ Lynk for this reason, just didn't think I'd need it yet. Plugged it in, the truck fired up and all was good...... :beer
Now everything seems...ok.... but when I switch tunes, sometimes.. the install may stall out and the same behavior as above... not crank, tons of codes.
Should I be worried or is this typical "modified truck" / "weekend warrior" risky business? I would like to not ruin my multi-thousand dollar new toy.
Thank you in advance for all your help and replies. Please forgive the ignorance regarding the truck as I'm a new enthusiast. I have a slightly mechanical/plant/engineering background.
Kind Regards,
Vash
