So I've been trying to fix my '88 Vmax for the last month and still can't fix this issue with the fuel pump. It started out when I took a small fall at ~10 MPH and it seemed to move around the diaphragms in the pump which led to a loud clicking sound from the pump. So I then took apart the pump, found everything to be OK and put it back together and it still didn't work but now it decided to not click at all. Then my pump relay decided to take a shit and after I replaced that relay, my pump now is acting up. Instead of it clicking like it's supposed to it is now buzzing. There is the video of my issue. I have already purchased a different pump but it came DOA to my dismay so I have to send it back for a replacement. Is there anything left other than replacing the entire pump? Any advice would be appreciated. Thanks!
