The car wont start because of the anti-theft system (PATS). The cluster and the PCM are coded for each other. After a cluster replacement, the PCM needs to have the ID of the cluster programmed inside.
The other option is to disable PATS with a programmer.
Why are you swapping the cluster? Hopefully it is not to make the car appear to have lower mileage. That is fraud. FWIIW, the car's mileage is also stored inside the PCM.
