Having problems starting my 2009 848! Battery checked and all good turn ignition on and all looks and sounds Normal, press button light goes out then nothing! Thought it may be an immobiliser problem any suggestions??
If it is an immo problem you will have a MIL on the dash. Initial thoughts: 1. Engine cut off switch 2. Battery duff 3. Side stand switch 4. Starter relay
Ground wire on ecu, have you removed by any chance? Did this last time same issues, put it back on then fired up straight away.
