Here is the problem:


  • Bike has spark, pour petrol into top off throttle bodies and turn over it will try and start.
  • Fuel pump is priming and pumping fuel.
  • Fuel line and Rail are clean.
  • Bike has been at dealers and put on diagnostic kit and come back with no faults.
So why am I not getting any fuel through Injectors??

Before you say anything have purchased second complete Throttle body assembly inc rail and injectors. Swapped over and still no fuel. Yes there is fuel in tank.

relay or fuses. Check a wiring diagram and see if you have power to the injectors. If its still under warranty have the stealership do it.

fuses/wiring ok, same relay powers pump/injectors so there for in pump is priming then power is getting to injectors. All elecs have been hooked up to dealership diagnostic kit and no faults.

You need to check all your safety devices, for example the Tip over sensor can cause this condition, kickstand etc.

Take your volt meter out and see if the Injectors are getting power. Just cause the relay is working don't assume it is getting power. You can have a bad connection in the plugs. Secondly Iif you are running any type of piggyback system like a PCIII make sure that it is working properly. If the signal from the ECM gets to the PCIII and there is a malfunction then the PCIII won't relay to the injectors and you would have no troubleshoot codes or FI light. Its strange that all 4 injectors are bad but it could be a possiblility. Well you can pop off an injector and take it to a shop with a flowbench for injectors to see if they are clogged or defective or not. Last it may be the ECM malfunction. Maybe its not sending signal to the injectors to pulse. A thought and it might not always throw a code or light. Good luck!
