Starter spins motor, no crank.

Update: I charged the battery, reinstalled. No error codes in dealer mode. The bike cranks (still no start). Pulled the tank and top sparkplug to check if its igniting. Consistent spark noted when cranking engine with starter. fuel supply related issue...? I did a thorough visual inspection of the wiring and connections (nothing visually evident of loose or bad wiring). Fuses all look okay. Next step, I will test the fuel pump relay... if good, I will check power at Fuel pump. suggestions??

As you have spark it can only be fuel or air.
You said the fuel pump primes.
Fine, but does it flow fuel?

Quick fuel pump flow test.

@thadscottmoore, FWIW, you can leave your bike in dealer mode until you are happy that everything is working or you can ride it indealer mode to see whether any further / other dealer mode codes are displayed.

Have you sorted the C23 code that you reported in reply #19? Until this TOS code is sorted, your bike will start and cut out within seconds each time try you try starting the bike. https://www.stromtrooper.com/threads/tip-over-sensor.30361/ and https://www.stromtrooper.com/threads/by-passing-bank-angle-sensor-tip-over-sensor.6468/ are worth a look

Removed the TOP, tapped it a few times and reinstalled it. Currently in dealer mode, there are no codes displayed. Motor spins over, getting spark. Will pursue fuel side in the morning. Thank you for the input.

Did the fuel flow test - that warranted pulling the fuel pump... but, found the issue in the process. Water in the fuel. Drained the fuel, cleaned out the tank, removed and blew the fuel lines out. Reinstalled everything. Added fresh fuel with some additive. Starts and runs again! 😁

Glad you found the issue. ✔
You said this occurred a couple of days after filling the tank. A fuel station to avoid from now on?

I think the same. It had also rained that day... I will look at replacing the fuel tank hatch seal too.

Glad you figured it out. It might not hurt to add some HEET to grab any lingering moisture in the far recesses of the tank.

In addition to the tank seal, be sure to check that the drain hole is clear. You can blast that out with parts cleaner to be sure. If you park under trees normally, suggest moving the bike out from under them.

I did add Heet to it. Changed oil/ filter, pulled the fuel pump- cleaned the filter. Thank you for the input. I just purchased a waterproof bike cover. Its normally parked in a parking lot with no overhead cover.
