Chevrolet Silverado 2500 HD Classic LT: Just installed 8 new

Customer Question

Just installed 8 new injectors on a 05 chevy 2500 hd 6.6. Now no start. Truck came in running now won't run. Have bled lines numerous times. Checked codes and have a u0105. Checked for injector pulse and don't have injector pulse. Checked 2 grounds and 2 power wires at FICM. All are good. Also checked signal wire between ficm and ECM. Light blue wire. That checked fine also. I believe I have a bad ficm but don't understand why. No codes and running fine before injectors were replaced. They were replaced because of an intermittent knocking noise from upper engine per direct hit.

Hello, I'm Cam.
Can I get your first name please?
Sorry to hear about this issue. Was the engine washed before or after the repair?
