So everything was normal, and I just stopped to get some fuel and shut the truck off, fueled up, go to start the truck, and no crank, no start.
My RaceME Ultra screen doesn't come on, and all my dash warning lights are lit up EXACTLY as it does when reflashing the ECM loading a tune.
Since the Ultra screen is just black, I went to unplug it to plug in the little code reader that I keep in my Jeep, and while unplugging the Ultra, the red light will flash the same when plugging it back in.
So I was able to get a PO2E9 code when I first checked it, and now even the code reader says "no link," but it does power up, so not the fuse for the OBD2 port.
I've gone through and checked all the connections for the whole Ultra tuner, checked OBD2 port wires, nothing.
Anybody got any ideas?
