I wonder if the truck would run a default method if say O2 sensors and MAF was disconnected or reset with battery and disconnected. I'm guessing since power was disconnected it has no default running mode, I'd heard some vehicles can do that in the event all failure is detected, course may take a bit for it to make the change needed to operate, if it is capable at all.
air box may be dry, but all it would of took was a mist of water taken in at startup, not really that much different from issues like what is seen with the 3.5l turbos sucking in water going to limp mode.
Not sure how I ended up on here though, just came up as a random post on my phone below the 15'forum I was posting in. Hopefully get it working
Ok guys, just posting this so it might help other people solve their issues. Turned out that the upstream O2 sensor on passenger side got stuck to the exhaust pipe and melted causing all the issues I had, well almost all of them, i replaced O2 sensor and pigtail but then my truck threw a P0443 (Evaporative Control Valve Circuit Malfunction), checked the valve and nothing, then doing some research online some people suggested checking for blown fuse, specifically F32, checked it and BOOM! It was blown, replaced it and no more codes and runs good again. What a pain in the butt uh? I finally figured it out! Yay
