  2. Start by checking if the fuel pump relay is clean, it's tucked behind the battery box

  3. Checked out the fuel pump relay it looked ok terminals clean but i put a new one on ,£3.70 was hoping for a cheap easy fix
    Have cleaned all electrical connectors that are in view
    Still got that dreaded orange light on and same fault codes
    Looks like a bit of dismantling is on the cards

  5. I've had those two error codes nearly every time something's gone wrong with mine.

  7. It was the fuel relay after all .When i first put the new relay on and turned the ignition on i thought the orange light would go out if that was the fault .
    I could hear the fuel pump priming but not with the old relay in so i tried starting and it fired into life the light went out and the error codes disappeared
    Relief
    Cheers

  9. First of all i hope the issue is sorted.

    I had the same error codes with my 999. I thought it had been fixed twice but twice the bike ended up on the back of a tow truck.

    If it does return as mine did around 100 miles later then the fix for mine was a repaired ecu and fix a damaged wire in the loom it self. Took some finding by the mechanic.
    i've always suspected I damaged the wire probing around the behind the battery changing one of the relays as a precaution during one the services I was doing :-( Good luck mate.

  10. To avoid a repeat performance, tie the relay into a grease-filled finger of a rubber glove. :upyeah:
