Mine sits 6 months or so for last 4 years. 04FI TCb. Totally stock. 50k on it.
When I get to VA, I put the battery on the maintenance charger for a few hours and put it in bike. I syphon 4 gallons out and refill with new fuel.
It takes a good 15 minutes to get oil bag refilled driving at neighborhood speeds.
It also is extremely hard to get it to start if you don't make sure it's running and both cylinders are clear if you let off the start button too soon.
I have always thought it tends to flood its self. Opening the throttle a tad clears it.
Read this to understand that P55Pb. It's not an error code.

It's possible, enough condensation in bottom of tank got into line from pump to electors. Hit it carefully with misted fuel spray in front of throttle body to run it enough so line clears.

Just because it's EFI doesn't mean that the basics still don't apply, need fuel , spark, and compression. Figure out which one you don't have, then dive down the electronic rabbit hole

What JP says makes sense.. What DLJ is reading is not an Error code.. Chances are that the engine light is temporary likely a crank sensor code.. Motor can throw a crank sensor fault if the motor stalls. If you hit the starter, the ECU see the crank signal and clears the code. You are back to fuel pressure / fuel. My guess anyway.

Update #1
Got some other rat killin done and had time to get back to the no start bike. Cleared the code that was not a code.
Got spark, good spark. Fuel drips from the tank quick disconnect when disconneted and sprays when depressing the valve. I have not confirmed fuel is getting to the throttle body; can't get to the disconnect for the supply line from the tank, too much crap in the way. I did spin the motor over a few times and in the process found front plug with crack in the exposed ceramic, spark was arcing outside the boot, replaced it. Neither of the plugs was wet after several spins; not sure if that means anything but I expected them to be wet with fuel. Not sure where to go from here.

That's K ohms.. 900-1100 ohms.
DLJ,
Squirt fuel in the intake. See if the motor tries to start.

Hold open the throttle blade and give a 1-2 seconds spray of brake clean.
Let throttle blade close and hit the start button.
See if it tries to fire up.

I have been told that the code was not a code (P55Pb); doesn't look like a Harley code but WTFDIK. When Googled fuel fault was one of several issues that showed related which is why I was thinking a fuel delivery issue and it still might be. The code has been cleared but no change. When I was cycling the ignition today, one cylinder fired for one revolution twice so I am thinking the solution has to be something simple.
Thanks to those that have responded.
