The battery is new. When the car give the command to start the alternator to charge is when all this happens. Using the tech 2 when you turn of the alternator no trouble, then you give it the command to charge about 30 second after it kicks in the car start to sputter then dies. Now if I remove the battery cable from the alternator and using jumpers cables attach it to another battery and give it the command to charge the car keeps running. But the moment you touch the another jumper cable from the main battery to the alternator it sputters and dies. I have run the wires from the alternator all the way back to the ecu. All intact no cuts or breaks. Could this be a bad ground somewhere? I am at a loss. GM said it was the ecu they put a new one in did not fix the problem. Then they told be since it was not throwing any code faults nothing more they could do. So right now I have a new alternator (not reman) new ecu from chevy parts, new battery from Walmart and I still have a car that will not run.
