After many minnesota winters, the body of my grand prix rusted to swiss cheese so i swapped everything that was good on it into a 99 buick regal ls. engine, trans, suspension, pcm. i rewired the engine with a 99 regal harness and tried to start. no crank, no fuel pump. security light stay lit. plug in hp tuners. and it reads the pcm as my grand prix as it should. i think tho, it pisses off the bcm that the vin's dont match. am i wrong? i tried to relink vats but that didnt work either. Id like to change the vin in the pcm to the vin on the buick but hptuners says "unlicensed vehicle" and wont let me change it. i dont have the old pcm out of the regal so i cant try that :/ any ideas? i can control the fans and everything else in the scanner while linked but no start :/
