No COM OBD2 No crank no start

I have a no start no communication to the OBD2 port. It will however crank by jumping the starter relay. The battery is new and has a fresh charge also replaced the starter motor and cleaned the battery terminals and ground points in several locations. Replaced the braided ground cable that goes from the firewall to the block. The ECM/PCM is good.

I discovered the electronic suspension module is bad, located above the spare tire I disconnected it and immediately got communication to the OBD2 port. Which I did not previously have. The trouble codes in the scan were as follows:

U0100 Lost communication with ECM/PCM
P069E - Fuel pump control module requested MIL Illumination
P0700 - Transmission Control System (MIL Request)
P2271 - HO2S signal stuck rich bank 1 sensor 2

With the electronic suspension module disconnected it would not crank..

My question now is if I go ahead and replace what I believe is a bad suspension control module...I pretty sure my suspension compressor is bad and seized up. I do not want to replace the module with a new one and possibly fry it with a bad compressor.

Questions:
1) Is it possible to fry the new module with a bad compressor. The system was fine before even though my suspension compressor was bad.
2) Should it start with the electronic suspension module disconnected?

Any accurate advice is appreciated.
