Hi all,
Apologies if this has been covered (I did a search but couldn’t find..)
My 2007 990 SD is giving an FI warning when I switch ignition on; 3 long 3 short flashes - manual says its; Injection Cylinder 1 - circuit fault. It turns over but won’t start.
Is this likely to be a fuel injector just a bit gummed up as it’s not been used in a few months? An easy fix..? How hard is it to get to..?
Many thanks,
Steve

Injector valves are mounted on throttle body - page 7-44 of rebuild manual re electrical checks.

Tank isn't too bad. I found a slim chock of wood that fits in there and gives me enough leverage to flex the tank back in and hold it there whilst I get the bolt back in.
With TuneECU you can actually test the injector operation (according to the website), but if you look on youtube there are plenty of videos of people showing how to clean injectors when off the bike.

Update:
In case anyone is interested.. problem was solved.
The fault turned out to be damaged wires on the Big Grey Connector (BGC - located under the frame to the right of the ECG behind the steering stem). For those who don’t know; it basically connects all the fuel injector wires (15 in total) to the ECG.
It’s easy enough to get to, the biggest agg was getting the tank off or, more accurately, getting the tank back on again... https://uk.farnell.com/itt-cannon/13201 ... dp/3126301
I strongly suggest checking before using them, I couldn’t see how to make it work and they didn’t respond when I contacted them after I purchased.
To sum up; I suspect if you get the same FI warning I got it’s very unlikely to be a fault with the injectors (although I cleaned them anyway) - so check all the wiring thoroughly; on the 990 much of it is oddly routed/exposed and so prone, certainly after 13 years of use, to fail..

Minor correction - BGC and (all?) other connectors are available from KTM - see Spare Connectors here viewtopic.php?f=18&t=16897
