The trouble is on a 2000 vfr 800 from Canada. I purchased this bike in June and when I turned the key I had to flip the kill switch 2 or 3 time for the pump to start priming, then the FI light came off and bike started fine. Now the pump prime rarely when I turn the key or flip the kill switch. I can always crank the bike. The engine stop relay clic when I turn the key but not the fuel cut relay, except rarely when the pump prime obviously. No HISS on the bike. I tested the engine stop relay, the bank angle relay and the fuel cut relay. They all seem to work properly. The kill switch works fine. When the pump prime I got 12 volts at the fuel cut relay (Brown/Bl and Bl/white), and nothing when it doesn't. I checked the continuity between the ECU and the fuel cut relay (the Br/Bl wire) and it's ok. I also checked the continuity of the Black/white wire that goes from the engine stop relay to the fuel cut relay and it's ok. I have 12 volt between the black and white wires of the fuel cut relay and the ground. It looks like the ecu fails to give its signal to the fuel cut relay when I turn the ignition on. I want to be sure that the trouble is with my ECU before purchasing another one. Is there anything else that can stop the ECU from giving it's signal to the fuel cut relay? Or Am I missing something? Any help would be appreciate!
