I bought a GMPP parts harness and computer and the car wont start. I put a cam and ported heads and blower on it so i sent the ecu to Faster Proms to be set up for 96 lb injectors. he car starts for 1 sec and then it quits and wont restart till you disconect the battery then it will start 1 time and run for 1 sec or so. The gas pedal wont work and it had a code of P651 and P512 anyone know where to start? I have HP tuners but im not sure if its a prog thing or a bad harness or part. Who can help me? I need a color wire chart to start going thru the wire harness its a 2010 CTSV engine with the 19354336 gm harness hooked up to it with 19259294 computer

Do you have a matching gas pedal, tac and throttle body? Has Vats been disabled?
