2001 Hyundai Sonata Theft recovery, busted ignition, no spa

I have my 2001 Sonata v6 2.5 GLS. I bought it cheap as a theft recovery, where they busted the whole ignition under the column. This car has a replacement engine in it that has been tested to work with a 6 month guarantee, and a replacement ECM, which also was tested to work. I have no power in or out of my coilpack, and no fuel. I suspected this was the ecm, so I replaced it, as my old one did not give a signal to the code reader, but now the new one is too. Does this car have an immoblizer possibility, and, if so, how do I reset it. If not, would towing the car to the dealership to reprogram the ECM work to get this going? I have already ruled out crank sensor, as it did the same on both engines, and wiring is all good, also, no power to and from the coils.
