Default possible ecu issue-down time

My fuel pump controller seemed to malfunction-pump ran continuously at key on. when the controller was swapped out for a spare one, the pump operated normally, but there were still some problems loading changes to the maps via AP. Upon further work done (swapped out injectors), fuel pump failed to operate at all (with either the original or spare controller). All this went down while at my tuner (original key on problem may have been ongoing previously) , so I'm sure they checked the obvious fuses and whatnot. Long story short, my tuner consulted with Cobb, and they decided it was best to have my ecu, AP, and cable sent out to Cobb for testing. Any thoughts? by the way, my ecu had been swapped out by the previous owner of the car for reasons unknown to me. its a 2005 ecu and my car is a 2004.
