I bought an 04 crown vic. they guy told me all it needed was a fuel pump and stupid me didn't check for power or anything and just put a pump in. well... it wasn't that I seem to have power at all the fuses but can not get any communication out of the pcm got a different pcm it wasn't that. someone had told me something about the security system runs through the radio? I have no idea I have never heard of that before. can anyone give me any tips or hints where to start with this thing?
