15 chevy silverado NO START after calibration urgent HELP!!
So, I made some adjustments to my virtual VE table and flashed the ecm calibration, after it was completed I shut my truck off and then tried to start it and nothing. Seems like its not getting fuel. The ecm is keeping not commanding fuel now from what i see. Also, my compass on speedometer is saying cal and my outside temperature on the radio is not working. They have always worked and did before the flash. I have tried putting it back to stock well the stockish one i have which has very little adjustments to it. Ive tried 4 other tunes i have for my truck that's ones Ive been messing with and saving them. None of the tunes fix the issue and Ive tried write entire.
I'm getting a lost comms with abs module code but at one point i did a lost comms with a few other modules but now those dtc do not show up. I cleared them thinking it would help, should of got a picture of them. I have tried unhooking the battery, held both pos and neg together for 30 secs. Let the truck sit unhooked from battery and hooked up. Nothing has helped me yet.
Battery voltage is good even tried it hooked up to another vehicle.
Here is the tune i tried flashing into it and a log of trying to start it. i added some extra channels for this issue.
any more info needed please let me know!
any help would be appreciated
