Anyone know if they are off for the holidays? Ive tried the only 2 #s that i have found.
Not bashing or trying to cause a disturbance by anymeans, just seeing if i should wait till later in the week or if there is another way i could get ahold of some one...

Flushed/changed coolant went to start threw p0192 codes and then p0193 codes (both for low and high rail pressure sensor voltage) started trouble shooting, flashed back to stock, code stayed on, went to flash back to my tunes and getting bad sn/ $0534 though maybe it was due to codes unhooked batteries to start ohm testing. Figured out it was sensor, replaced no codes all is good but still gettin 0534 bad sn. Autocal reads tcm info just fine, vin and sn, pcm says n/a for vin and all zeros for serial. Reads pdis and clears codes and such just wont flash not even a reflash back to stock pulled radio fuse, seo ign seo acc. Hvac.... Im lost its an 01 and from what i hear i might be in trouble with the ecm
