    L99/6l80e swap no spark!

    I have a l99/6l80e compete out of a 13 camaro. I sent the ecm pcm for less and had vats turned off and the evap stuff. I removed the wires and plugs for the electronic rack, and evap plugs brake booster sensor.I've check over all the grounds I have 12 volts to the ecm when cranking. The fuel pump relay is turning the pump on as it should even the pedal moves the throttle body but still nothing. Could it be something done wrong in the tune?
