FYI, i tried turning the car to ig1 7 times, each time disconnecting one of the 7 pgmfi main relay wires before turning the key. On all but 1 the fuel pump never turned on. The one wire that could be disconnected and the fuel pump still turned on was the blue wire, #6 on the honda shop manual that goes to the ST switch.
If you disconnected any one of the other 6 wires, the fuel pump wouldn't turn on.
You may be thinking well what about if the car is already started and running and you disconnect one of those wires (via a switch), well I plan to test that on Thursday, while having my multimeter connected to the fuel pump and will report back the results.
