the ecu doesn't power the fuel pump. it just controls the negative on the relay.
the fuel pump receives power from the FI circuit. the fuel pump relay is powered from the engine stop relay which is controlled by the kill switch and the bank angle sensor. if the engine stop relay doesn't click when you toggle the kill switch, there's something wrong between the kill switch and bank angle sensor.
if the engine stop relay does click but the fuel pump relay does not, there's something wrong between the fuel cut relay and the ecu.
look up a wiring diagram it's very very simple.
