More details, please.
Was the bike running fine for weeks before this? Was this the first time you tried to use it in a long time? How old is the fuel?

 

2006 model
Ran fine for weeks. No issues.
Daily ride. Not stored.
Filled tank a few days ago.

 

As @BikeMikeAZ says, the more details you can provide the better responses and help you'll get.

 

The Gen 1 DL650 had a separate kill switch and starter button. On those bikes it is possible to turn the engine over with the kill switch turned off.

Check your kill switch.

This is not accurate, at least for my own '06. The starter will not turn with the kill switch set to the 'stop' position. If you can hear the fuel pump prime, the kill switch is not a factor.

My bet is that the tipover sensor is either not secured in place or is not in the correct orientation, probably happened during the battery swap as it's right near the battery box. You can get positive confirmation of tripped TOS by putting the ECU in dealer mode, it would show code C23.

If that's not the culprit, continue on to confirm you have fuel, spark, and air.

 

Does the fuel pump prime when you turn on the ignition?

 

Yes

 

It was raining that day. After it died... my first action was to test the battery. It initially had 12.7v. When I turned the key on- it dropped to 8v. I pulled the battery and took it to get tested at auto parts store. It showed bad battery on computer. I exchanged it - hoping that was the culprit. After reinstall, it cranks the motor without starting. I thought maybe the rain might have something to it...

 

If the tip over is out of place the bike will start and run for a second then it will cut out, it will do that over and over again.

Do you hear the fuel pump prime each time you turn the ignition on ?

 

Fuel pump is priming. I will check the things recommended on my next day off. Thank you for the info.

 

When you do get around to inspecting the connectors, do remember to include the connector at the end of the lead from the stator cover that is from the crankshaft position sensor.
One would expect a FI code to be displayed during cranking... but only displayed when in dealer mode, https://www.stromtrooper.com/threads/c-12-crankshaft-position-sensor-issue.74191/ and https://www.stromtrooper.com/threads/06-ckp-sensor-coupler-wires.368585/

For the low down on dealer mode, https://www.vstrom.info/Smf/index.php/topic,7061.0.html

 

Thank you

 

Ok, update...
Put into Dealer Mode and pulled a C23 code. Bike has never been laid down... pulled the TOP and shook it and reinstalled. Upon reinstall- tried to start the bike and suddenly no power, no lights on dash. Pulling the tank now to go farther down the rabbit hole. I pulled the TOP sensor and reinstalled a second time with "UP" facing up - jiggled the wiring around that area... no power. Checked fuses- all good. Going to check that green wire that was mentioned...

 

You also need to check the ground wires in the big plug.

Bridge the 2 big terminals on the starter solenoid were the main 30a fuse is, the bike should crank (it will not start) that will test the battery and connections including the battery ground.

 

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.

 

I will look at replacing the fuel tank hatch seal too.

Unless your drain pipe is plugged, the seal shouldn't make much difference. The tank has a raised lip. My seal has been bad for years with no extra water in the tank. If the drain gets plugged though, then it's a different story.

Try pouring some water around the tank opening and make sure it drains quickly.

As far as the hatch seal - I did just replace mine with a Honda seal: Honda part# 17525-300-000. If you want to do it, I'm happy to give better instructions. Actually, maybe I'll post it here.

 

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.

 

2014 650 V Strom: I've had that problem twice. 230 KLX once. Friend with Yamaha Tenere once. We think it is ethanol gas collecting water after sitting 3 or 4 weeks. We had to hold starter long enough to push water through injectors before starting. They ran fine after a few minutes of running. Try Stabil for ethanol gas if it will sit over a few days and it should help.
