Hello and welcome to JustAnswer!

I believe the issue is that a used immobilizer module was installed which does not match your ECM. The keys, immobilizer, and ECM are programmed together and all have to agree for the engine to start. The replacement immobilizer module is going to need to be programmed to the ECM using a high end aftermarket or dealer scan tool.
