Hello and welcome to just answer. Your PCM has failed it is not a security system problem. The PCM (engine computer ) is not allowing spark or fuel and is also preventing the gauges from working. If find no blown fuses. Then have the PCM replaced. I have seen this exact same thing before and am 99% sure that this will fix it.
I hope that this information is helpful and please let me know if you need further assistance.

Hmmm, jump starting it backwards could be the reason. That can kill controllers immediately. Let me know how it goes.
