On these older Hondas and Acuras, sometimes the main relays fail but can be brought back to life without having to replace them. In the past you could tap on them and they would start working, that's because the solder joints crack and create a cold contact, tapping on it closes the circuit and it works temporarily. Simply heating the solder reconnects the circuit and fixes the problem as I demonstrate here.
