need help please gt650 !
« on: March 01, 2012, 01:09:12 PM »

My 2010 efi gt 650 won't start. Ive replaced battery , regulator, wiring and ecu
I recently had problems starting once I replaced those parts it started okay
Then I inspected the fuel pump and replaced the coolant resovoir tank and now won't start. Spark plugs okay.
It true to kick over but seems like it won't actually fire up. After trying to start for a few seconds red fi indicator comes on.
At wits end need help Thankyou in advance

have you checked the code it says?
if you're not sure, under the rear seat, on the left side is a 2 pin socket. short it out with a paper clip and turn the ignition on. make sure the kill switch is on.
It should display a code..eg: C42. download the service manual from the Sticky in GT650 section and check the code from there.

you can only check the code, if the FI light is on.



Mods: Can this thread be moved to the GT650 section? he may have a better chance of getting help there.

I've found the plug it has a black wire and a white and black wire coming to it ?
What does shorting it out do ?

here's what i posted up in another forum a lil while ago:


you can check the error code yourself at home.
open the rear seat and on the LHS (standing behind the bike) under the rear fairing, there is a white 2pin connector. put the bike in neutral with the kill switch to on and turn the ignition on, so the dash turns on. wait a few couple of seconds, till you see 0kmph on the dash and then put a paper clip in the connector and about a second or so later, you should see the codes on the screen
it should tell you code in terms of....C41 etc..
if there is no errors recorded, it'll just show a C or C00
and then look it up in the service manual.
here's the link:
you're after the GT650 EFI manual.

here's the how to short it out:

that is the plug. the pice above will show you how to do it.
Shorting out the plug, shows you an error code on the dash and then you can check the error code in the service manual. it'll tell you whats faulty and also, possible ways to fix it.

just throw the error code you're getting and i'm sure someone here could help you out with it.

G'luck

I've done that in came back with c12 which says pick up coil malfunction but I did the ohm test on it that it says the manual and it said it was ok. I didn't test the ecu coz my ecu was different to the one on the diagram plus the ecu is only 3 months old

that sure means there is no error there. That being said, if yours is a '10 or '11 bike, with a Daewoo (have a mind blank?) ECU, it won't store the codes.

Codes will be there, as long as your bike's got power. The moment you turn the key, all the codes are lost.
