Inspect the coil wiring to make sure no wiring is shorted or damaged leading from the computer to any components especially the coils.If any damage is found it will need repaired.If the ECM was not programmed to your vehicle this will cause this fault here and the ECM has to be programmed by a dealer or repair facility that has access to programming for it to allow starting at all.I would have this done as well here.

Did you have the ecm programmed to your vehicle at all?
I apologize for the delay.
The smoke from the coil can cause ecm damage and on top of that the ecm has to be programmed when it is replaced in order for your vehicle to start and run properly.The dealer can reprogram the ecm but the ecm has to be installed in the vehicle with the vehicle at the dealer or a facility that has access to GM programming.
