9 blinks is the IAT (Intake Air Temperature) sensor. It's the one located on the airbox. Very common not plugging it properly or pinching the wire when lifting the tank.
11 blinks would be the speed sensor. Easy to check (just follow the wiring from the back R/H side of the engine) but know these sensors are known to go bad. Shouldn't affect vehicle operation.
As per fuel, you should carry out a fuel pressure/flow test.
To test pressure, you'll need a fuel pressure gauge that bolts straight into the fuel pump main outlet. Details on request and pressure should be 50psi.
To test flow, you need to disconnect the fuel cut off relay and short the connector. Lift the tank and disconnect the fuel return line. Put a scaled container under it and turn on the ignition for 10 seconds.
Flow should be 190cc/10 seconds.
Now, these bikes are quite prone to clogging up their fuel filters: in 90% of the cases I've seen (including my bike), a failed fuel pressure/flow test was due to a clogged filter. This is Honda-specific part: you cannot adapt anything else on the market.
Finally, it's possible your fuel pressure regulator is toast: very very common issue as bikes age but there's no sure fire way to check it.
You may try disconnecting the vacuum line from it and see if fuel drips from there, but I've personally seen bikes with a failed FPR which didn't drip fuel.
Shame on me, my heart is black.
