Hello, I have a problem with the 2008 690SM which I can't solve. It will start normal but while riding the FI light lit and engine stall. It can be restarted and keep going for a while and same happened again. It seems happen more frequent the longer I ride.

Also the dash warning lights will lit and needle showed self disnostic mode while riding but engine can keep running (riding).

When pluged in dianostic tool and said the fuel pump relay error and replaced the relay. The problem presist and I was advised to order and replace the whole wiring harness.

I have checked and cleaned most of the electrical connectors. The problem will not go away.

If anyone of you have experience in this matter, please share your view as I have no electrical knowledge. Thank you for your help.

Are they sure its electrical? The looms are know to chafe under the battery tray on the Enduro and where it passes down the right side of the frame. Strip off the tape and start looking. Personally the first thing I would look at is fuel pump, in tank filter and injector. You can also get yourself a copy of Tuneecu and a cable do the diagnostics yourself.

The wiring harness looks in good condition from the outside and insulation is still flexible to the touch. I have started the engine and wiggled around different areas of the loom and there is no sign of abnormal. I borrowed a dianostic cable and smart phone from a friend and it showed the following:

This is when engine is running

This is when enhine not running

I have no idea what it means or to tell if anything is wrong.

This is the error code after I have already replaced the fuel pump relay and I think it means there are some kind of short circuit at the fuel pump relay?

I've had P1231 on cars more than once, throttle sensor position. Cleaning the throttle body with carb cleaner, and resetting it fixed them. Not uncommon on older Vauxhalls with K&N filters. Oil would shit up the Throttle body.
I don't know much about that model bike, so you'll need advice from one of the guys here if what I'm talking about is even applicable.

The other error, Low Speed Fuel Pump Primary Circuit Failure, no idea. Pump fucked?

What’s the sequence of the FI code on the dash?
I have only take notice of it once when FI lit and engine stalled. It flashed 4 times at 1 sec. interval. There should be other time when stalling and I was in the middle of traffic and too busy to restart the engine and move on.

Thanks Dansin for the FI code. I may have misread the sequence that time. I shall give the bike another trial run and see if I can read the code again.

I have changed the fuel filter and checked / clean electrical connectors. The bike will idel with no issue at iddle for more than 15 mins but will stall while riding when FI light is lit. I have ran out of ideas what to check.

Mine did that too but after it stalled I could not restart it for about 10 minutes. After that it started normally until it stalled again after about 10 minutes of riding. After a long time I found the culprit being the earth contact of the ignition coil. They did not fully remove the paint from the frame and once everything had warmed up it stalled. There was also an earthing point behind the little plastic cover on the left side below the head stock that I cleaned.
It never stalled again. Maybe worth a try, its not much work.

Good luck!

Thanks for the pointers. I will try that too (though I have already cleaned the coil and negative contact behind the battery tray) again to make sure I do a good job.
Any other suggestion? Fuel pump not delivering enough pressure/flow?
