Reply To: GT650R Fuel Pump Fault

[Chris]

it’s been nearly a year since I last updated on the GTR woes….

shortly after my last post the bike stopped sparking,  it was running on the stand, and fizzled out.  Never managed to sort it out and due to having another bike, the 650 got pushed to the back of the garage.

Till now….

Recap,  bike was running rough with C41 error.  Had a new fuel pump, wiring loom and cleaned the injectors. Ran but then it stopped.

Today I managed to get a replacement ECU,  I put it on, turned the key and got c21 error.   I then checked the Pick Up connector, all looked ok, and Ohms are fine.  Reconnected and still c21.  I tried to start the bike and the c21 cleared!   But c41 replaced it!

noted the battery is now low so it’s on charge and will see what happens with a full battery tomorrow.

if I don’t get to the bottom of it this time then she’ll have to go :(.

might just try a replacement relay, even though I have swopped then around.
