Im doing an engine swap in a V6 truck and im not getting any fire, so i try changing the VIN from the 02 GMC 4.8 to the current VIN of the vehicle and i keep getting an error msg. when i try to write it. Ive followed the "help" file 3 different time and it keeps failing to change when i try and write the VIN. Any help is appreciated, TIA, Eric.

Truck still will not start, cant even write a calibration now. I tried to write the original PCM VIN back, thought that might fix the problem but i get a error msg (mode 3 erase failed - check 1 failed) I dont know wtf im doin and really need some help. Last night, the only way i could get it to write is go to calibration details and put in the V6 VIN. I tried putting in the PCM VIN and changing back to the V8 VIN in "Change VIN" but all i get is ERROR msg's. I dont know what else to do.... I guess ill waste more $$$$ and buy more credits and try to write the V6 PCM????
