I am doing an LS3 swap from a salvaged 2011 Camaro SS. I have the engine, trans, ECM and BCM installed. I am using a new Holley fuel tank with pump and an external filter/regulator return. The engine starts and dies in seconds. If I leave the key in the ignition position for some time, it does not start. After it starts and dies, I need to wait to start again. Attached are the DTCs. Any help would be greatly appreciated.
