I don't have an E5 ECU in stock so I can't answer that question, but you can with a multimeter. Just follow the pin for the fuel pump relay back to whatever the part is that controls it. Put your multimeter on beep mode (continuity check) and trace it back, it's dead easy to do. If the part is a discrete driver (3 pin part) like the B13/S13 it's dead easy, if it's been rolled into a array (long part with multiple pins) it's trickier to replace, but still not that bad.
