Yes, but I'm not sure how strong it is. The plugs were dry.
I will change the plugs anyway, its easy and cheap enough to do. I'm wondering if the fuel filter impellor has gone as I can hear it giving a very slight click sound that I don't recall hearing before. It could be that I just didn't notice it though.

Dry plugs indicate no fuel. Can you do a spray test? Remove one injector, try to start, and see if you get a good spray pattern.
I don't know how to do that, but I'll look into it.
I can generally work on things outside the engine but inside the motor and such I leave to others.

The injectors are mounted externally on the throttle bodies.
I've been thinking. The only thing that changed between January and June is that I had a problem with the Li-Ion battery over discharging because a connector on the (lithium-specific) charger wasn't connecting correctly.
Would it be possible that the battery could turn the engine but NOT operate the injectors? I do hear the fuel pump working when I turn on the ignition.

No. If you have enough electricity to turn the engine, then you have enough electricity to drive the injectors.
Assuming you:
1. Replaced the fuel hose on your fuel pump correctly with no leaks.
2. Plugged every wiring connector back in fully and correctly.
3. The fuse for the fuel pump is not burned out.
4. Reconnected the fuel hose connection to the elbow under the tank correctly.
Then it is most likely that you have a bad fuel pump. Given its age, this is not out of the realm of most likely.
You can easily verify this possibility by cranking the engine for a good 5 seconds and then get down and SNIFF the exhaust pipe opening. If you do not smell the very strong smell of petrol, then you have no pump pressure.
I would check the things I listed above again just to be sure, as a new fuel pump is an expensive part.
Good Luck!

Got any codes showing in the dash?
Thank you. There is no fuel smell, sadly.
I will try to clean the injectors to be certain but I think it is the pump :/
No codes :/ I'm going to check fuses and crank sensor next, then try to clean injectors.
If you have spark, the camshaft postion sensor is good.
I assume you've already tried this, but I read through the thread and could see no mention, so just in case...
on my B11, when I suspected I had a fueling problem, I just pulled the fuel line and turned the ignition on. the system will prime by sending two or three little squirts of fuel from the pump - you'll hear the pump as well. it's easy to try, and it will tell (though not definitively, pressure matters and is not easy to see like this) you what end of the system is giving you trouble. have something to handy to catch the fuel.
Ooh, easy to do as you say. I'll give it a go when I can next get to the bike. Thanks!
I Finally got onto this.
Right so the story so far:
Bike wouldn't start.
Li-ion down to 9v. I slow charge it.
Charged, won't start. Plugs dry.
I suspect filter hoses perished. I replace.
Still won't start, plugs dry.
I buy new AGM battery.
Take tank off for one more look see.
Derp.
I'm guessing I need to replace it all from tank to injectors? It's probably sealed at the T junction, right?

That is a specialized type of nylon fuel injection hose that requires specific tools.
You can buy it online but last time I checked they were close to $200 or more for the tool kit.
You may just be better off economically by far, taking her to a fuel injection repair shop and having them replace the damaged piece.

Same thing happened to me on my Stelvio, thanks to my overall inability. You can get the entire fuel line from Guzzi for $80
The price I see in the UK is £120 ($140), but I have a replacement piece of nylon hose. I'm told that I need to cut the old one off, warm the new stuff in boiling water, and then push it on.
Personally I'm not feeling too safe with that idea so will get it professionally repaired.
That hose is a bit like using PEX for plumbing. The hose will shrink back down to original size and make a tight connection. Try it first. If it leaks then take it somewhere. If the connection isn't good, it will show up immediately once pressurized.
EDIT: Just checked the fuel swirl, looks like I have to take the filter out again, it isn't sealed somewhere.
I am fucking over it with this bike right now.
Changed the fuel pipe, won't start either on the old batt or the new one. Plugs still dry. I used proper fuel pipe and clamps, didn't trust the cheap plastic stuff. Same internal bore.
I guess now I have the injectors cleaned and if no go, I send it to someone to sort it for me. I just don't get why it was a-ok in January and won't start in June.
To add to my annoyance, the MFD button has stopped working...
