Good idea about changing the fuel, before overthinking this; was the old fuel dirty?
And did the starter crank the engine over as per normal or was it slow to rotate the engine?
If there is not enough voltage available for the injector pintels to open up they may stick closed, just a guess.
If it is a fuel issue it should fire up with a spritz of brake cleaner in the air intake of the air filter under the rh sidecover.
Verify ( again ) that the fuel pump relay is energizing ( clicking ) every time you activate the red stop switch, you should hear and feel it making contact with your fingers.
Also try full open throttle start, it may work.
My cb1100 has refused to start once and stuttered into life for no reason a little while later, so it can happen after sitting for some time, don't know why.
5500 miles does not sound like a worn out pump to me, let us know your progress
