Can someone direct me to a video or show me how to check the fuel pump relay? Also, how to check what fuse is connected to the fuel pump? I looked in the manual and it didn't list it……or maybe I just missed it.

My Vespa is being picked up by my dealer on Tuesday but maybe I can do something simple to avoid that. 477 miles…….turns over won't start. No whir of fuel pump when ignition is turned on. All lights on dash the same…
