Your right, identifying ahead of time is the best way to go about it but on a wheeler, SxS, or snowmobile I’ve always been able to hear the fuel pump priming or at least the actual relay clicking.
Yep, now that I have learned to listen for the fuel pump, I don’t even hit the start button if I don’t hear the fuel pump run first. I even wait for the fuel pump tp build max pressure and shut off, before attempting to start the engine. It only take a second or two for the fuel pump to max out.

Most ECM’s just run the pump for a few seconds when the key is first turned on just to prime the pump, no guarantee about the fuel pressure. When the fuel pump or pressure regulator starts to go bad you may have to turn the key on, then off, and then on again for it to start

Good to know, but at least it confirms the relay is functioning.
