Member Contributer Grum Posted October 13, 2023 Member Contributer Share Posted October 13, 2023 Check Main Fuse B 30amp and its wiring. Located next to your Starter Relay. Are you hearing the Fuel Pump prime at every switch On? Quote Link to comment Share on other sites More sharing options...

Instead of guessing!! (Extremely poor fault finding, adding potential delays and wasting money) at least do some checks. You haven't bothered to do a thorough check of Main Fuse B as suggested! This fuse feeds all your EFI stuff and it is a common failure point, suffering from overheated connections and burnt wiring. (Refer to the above pictures attached). -Why not check the wiring and power to the Fuel Pump. Verify the Fuel Pump Ground is good back to the battery Negative. Is the pump electrical connector clean and making good electrical contact, any corrosion evident? - Remove the connector and power the Fuel Pump with some test leads connected to your battery, does the Fuel Pump run continuously while power is connected, does it's sound fluctuate while running? - You could also do the Pump flow and pressure tests in the Service Manual. Service Manual can be downloaded from this forum if you don't already have one. - When your engine dies is it virtually instant, meaning an electrical issue. OR does it cough and splutter as though it's starving for fuel? What is the quality of your fuel, could you have excessive water condensation in your tank, is it Ethanol blended? Have you tried draining the tank and adding fresh fuel? What is the state of your Battery? Is it healthy, how old? Are your terminals clean and tight???? Check the connections for your charging system, check the 3 wire connector from the Stator to your R/R and the output connector from the R/R, both of these can suffer badly from high resistance connections and burn ups. - Check the 4p Red plug to your Starter Relay, this is another week spot for poor, overheated connections to Main Fuse A, see attached picture. If you get the engine going immediately check your charging voltage at the battery both at idle and 5000 rpm should be anywhere from 13.5 to 14.5v. If you are not sure or competent in doing any of these checks, take your bike to a reputable Motorcycle electrician or mechanic. 3 Quote Link to comment Share on other sites More sharing options...
