You can see the ecmB fuse in the diagram, hot all the time. The gray wire voltage to pump motor, black is ground.
Voltage to the coil side of relay, dark green wire with white tracer, that voltage comes from pcm. The coil side of relay has to have voltage and ground or the relay won't energize. When the relay is energized, that line with the arrowhear on it, moves to the gray wire.
