i just swapped motors from a 20r to a 22r and for some reason i now have no power to my fuel pump. i am not running a pump on the side of the engine block, just one in the tank i think. it worked fine before the swap but now nothing. if i run power directly to the pump it pumps fine, but nothing when i turn the key. anybody have any idea what could be wrong? i took apart the fuel pump relay and it looked fine. anything else i can check? please help. thanks, aaron
