Default Crank but no start

Hello everyone

Im having a problem with my mazda 3 2006 model. I recently changed the engine(Z6) to a ZY one and now the car only cranks, it doesn't spark when i check the coils, it also says something like lost communication with the PCM. So i took it to the mechanic and it seems like they dont know what they are doing. Can someone help please?

Did you fit the ZY PCM?

Did you programme the PCM to the immobiliser system?

I didn't change the PCM, they did program the computer box but im not so sure about the pcm. The electrician i took the car to, says that its the harness, could it be true?
