So, yes the main relays on Honda's control power to everything, ECM power, fuel injectors, fuel pump, power distribution connections etc. Looks like the wiring diagram should be hot at all times at fuse #8 15A under the hood. Looks like the relays are behind the glove box. One of the relays will have one yel/blk wire coming out. This relay will also have a wht/blk wire where power should be hot at all times. Check for power at the wht/blk wire coming out of this relay (same wire coming from fuse 8). If ok, check for power coming out the yel/blk wires (same relay #1) while cranking. This powers the other, including your fuel pump. The ground for the fuel pump is just a blk wire, diagram says under the pass side seat.
