By chance are there 2 relays alike you can interchange to prove their functionality - one controlling the fuel pump, and another?

Unplug the fuel line from bottom of tank and re plug. Make sure it snaps in. You may just push up on it and get it started. This is pretty common problem. This is assuming you can hear the fuel pump running. The fuel pressure regulator could also be faulty, but much less likely. ECM doesn't have a fuel pressure code. I think it will show no fuel pump voltage code.

You narrowed it dwn to no fuel.
Should be more EZ to diagnose.
I will suspect cam or crank sensor

What do the cam and crank sensors have to do with not getting fuel?

Do you hear the fuel pump initialize when the ignition is switched on?
I would also check the fuel line quick disconnect from the tank, as mentioned.

OP...looks like you're not making any headway on this, and the myriad suggestions you are getting here might have you chasing your tail. My contribution is to suggest that it's time to get your scooter into the dealership or an independent mechanic.

When you turn the Ignition switch on the pump runs for 2 seconds then turns off if the CKP does not show the engine is running. Once the engine starts to rotate the BCM turns the pump back on:

It's helpful to know the DTC number you pulled and if it was in the ECM, BCM or ABS...I'm guessing U0100. Did it clear and then come back?

I gave up trying to decipher his messages. No punctuation, or anything to make it make sense.
