someone wired up the pump incorrectly. the reason your pump turned on when you put your radio in is b/c you supplied voltage from a "hot at all times" source into a "hot at ON/ACC" circuit.. which then triggered your incorrectly wired fuel pump
tomorrow I can help you on this further. but those are the basics right there
