91 honda civic

Hello I have a 91 Honda civic hatchback base model 1.5L and I am having serious electrical problems. My wife took the car to town and when she got back all the lights quit working and it just sits there and clicks if I don’t remove the main relay. But the main relay also controls the fuel pump. Have already replaced main relay can any one help me?

Maybe it’s just me, but your video has no sound so I can’t hear the click. But check your battery.
