2013 650R – Is it a Delphi or Daewoo ECU?
When you go on this forum, look at the Manuals section and download the one that matches your model (I uploaded every single 650 manual possible)
In that manual, read how to trick the ECU in to giving you an Error Code or count the blinks displayed by the Fi Red Light on the dash
Ie. If the dash says C23 = that would be oxygen sensor #2 (rear pipe oxygen sensor fault) , this is just an example!
It’s not spinning the RPM needle because the ECU is locked until one of the sensors on the bike is looked at or something is unplugged.
As Simon would usually say on this forum (he is an EFi wizard too) , you would need to disconnect everything and clean the plugs connecting all sensors on the bike with the battery disconnected for a while ( for the ECU to reset itself).
Or check the ECU plug too
Let us know the error codes you get , the manual also shows you how to test sensors on the bike using a pocket meter.
Yes you need fuel in the tank, the pump will be quickly damaged if you try to run it dry. (The dash will tell you if there is fuel = eg. 4 bars of fuel left)
A minimum of 3-4 bars of fuel is good. Any less isn’t good for the pump (fuel sloshes left and right while riding, so you want it submerged all the time)
