Yep. Car was running fine off a tune from frost back years ago. I sent that file to get changed a bit reflecting what I had done now with the SC and what not. Uploaded that tune before I even had the S.C. done because I didn’t want to start it without at least a base tune. I’ve got vcm scanner on it now and that’s the only code. I’ve got fuel pressure but still no injector pulse but 12v at the coils. Would this code effect that or do I have 2 problems?

Ok.. How do I tell if it’s bricked ??. I uploaded the tune again and says completed in green but still the same outcome. Would a bricked pcm cause all the fuel pressure and injector pulse issues ???

Doubt that wiring has anything to do with it as long as the pcm is getting battery voltage...
My guess is that you were switching to a 2 or 3 bar OS and did write calibration or other error during the flash process and now the eeprom is corrupt

You may have hit the nail on the head. I never used hptuners myslef before and when I first received the tune i did "write calibration" instead of "write entire". Then the second time after talking to my tuner I did the write entire for my baseline. Would that dumb mistake brick my computer??
