Chip fried my pcm.

Hey everyone I have a 2002 F350 7.3 l diesel. I made the mistake of installing a cheap chip in the back of my pcm. Now i believe the pcm is fried. I will be doing circuit tests later today but i can not communicate with the pcm on the scan tool and it failed a network test. Does anyone know of a place that sells them. My dealer says no one in the country has one.

Did you check to see if the PCM was receiving operating power?

Does the check engine light come on when the ignition switch is turned from OFF to RUN? If so, it's getting power.
