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?

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?
