Reply To: Bike won’t start – GV 250 EFI 2015
For a 2015 Delphi, you said 10-5-10-5-10 or 1-7-1. I must assume 10-5-10-5-10 = ISC Error (Idle Speed Control Valve issues or errors or not detected etc) 1-7-1 is not found , the closest i can see is 10-1-1-7 = ET Sensor (Temp Sensor in the engine front cylinder) (Malfunction / Low Voltage) , it also says possible ECU malfunction or wiring harness. The service manual will dive deeper in to the codes i mentioned as there should be a diagram on how to check with a meter too. RO Sensor = The wires will be hidden in the harness if previous owner has cut it off ? = It is always by the battery area where the tank sits on, always, see where the 2 bolts of the tank screw in to? It is directly under there , very well tucked in and almost hard to access but it is there , it is also before the solenoid ball , then the battery box appears, right there in the center of the bike is where the RO sensor usually sits. Sometimes i get a hard time removing it myself to swap for another one.
good news! Bike now starts. I took it into my local shop and the button was just broken. The bad news is that I’ve still got a check engine light and the fuel pump continues priming (loudly) while the bike is running. I believe it’s because of the Black cable with a white stripe that connects to the voltage regulator. It’s got a hole that I think shouldn’t be there. I’ll try and attach a picture.
- According to the manual, it does connect with the fuel pump so hopefully it’s priming constantly because it’s not getting enough power or something. So I plan to pull the cable from the plug, cut it, strip the end and reattach it. Is that a bad idea? Should I connect it a different way?
(Thank you for all your help so far btw, I would’ve long since given up if not for this forum.)
