919 fuel / electrical issue

Hey guys. Brand new to the forum, and I'm already lucky enough to have my first problem with my 07 Honda 919! Hope you can help.

-Bike sat for the past couple months in cold weather (out of the elements)
-Tried to crank, and battery wasn't getting it done. Strange electrical symptoms, gauge calibration resetting and jumping, loud CLICK CLICK CLICK CLICK...
-Put the lead acid battery on a trickle charger, but it almost immediately went to "Fully Charged" indicator. No juice.
-Bought a new lead acid battery and installed. Upon turning key to ON, all lights and gauge calibration function fine, but I no longer hear the hum of what I always believed to be the fuel pump.
-Checked 20A FI fuse and it's good
-Checked some other fuses to be sure. All good.

My FI knowledge is very limited. Seeking advice on how to proceed / what I may need to replace.
Thanks in advance.

Did you check the kill switch on the handlebars?

Does the bike crank over and not start or does it not crank over at all?
How did the bike run last time it was used? Was the bike stored properly (is the fuel fresh or was it treated before storage?)?
If the bike is new to you, do you know for certain the maintenance history?

Sorry for the ambiguity.

To be clear, the bike will crank all day with the new battery, but will not start. My assumption is that it's related to the lack of the FI hum when I turn the key to ON position.

The bike started and ran great last time it was used. Last time it was started up was about a month ago. I do not anticipate that bad fuel is the issue. To answer your question, 18K miles. Basic fluid changes and maintenance.

If there's no power getting to your fuel pump, that will definitely be a problem. The 919 fuel pump isn't loud (ever heard a Buell pump?), but it should be audible if you listen for it.

Very odd that all was well, but after just needing a battery, it'll crank but not fire at all.
If you can not hear the fuel pump start when you switch it to on/run with the key, then something is duff.
Likewise, if you can hear it start, but the engine won't fire when you crank it, something else is at play.
I suggest you try to narrow it down a bit more for everyone here:
Can you hear the fuel pump start when you switch the key on? (and the kill switch is set to run, not off)
Or can you not hear the fuel pump start?

No Power Commander, correct?

Have you checked your fuses? Maybe replacing the battery created a surge?

Finally had some time to dig in this weekend, and I came to a pretty firm conclusion.

-checked 3-wire harness at the fuel pump
-ground is good
-one wire provides constant power. Good.
-one wire provides the initial power when the key is turned. Good.
-all of these are operating correctly and the fuel pump is receiving correct power
-still cannot hear the fuel pump start up when turning key to ON position like I could before the issue started
-CONCLUSION: It looks like my fuel pump is bad

Just for reference, bike has around 22K miles. I plan to pull the tank and the pump tonight. Should I be testing anything else out before moving forward? eBay says replacements go for around $220. Any other suggestions to save a brother some money? I don't know much about these. Can they be rebuilt? Either by me or a pump repair kind of place?

Thanks in advance

I replaced my tired OEM pump with one of these 161931908435. Kemso pump, ebay. Cheap. The screen that came with the pump didn't fit the honda 919 fuel pump mount. I reused the original intake screen. The pump itself is quiet and does the job. The bike runs like well. Like a cut cat.

Stupid link didn't work. The pump is a Kemso fuel pump. They are on ebay. I think I paided around $40 Australian dollars. Supposedly made in Japan?

Much appreciated. Anyone know of any other aftermarket options?

This was posted in an earlier discussion on fuel pumps.

Late follow up. Success! Ordered the High Flow Fuel aftermarket option that Islandboy listed. Worked flawlessly. Straightforward installation. Back on the road in about a day.

Thanks again.
