I have a very nice 2004 Breva 750 that has always worked well until I came back from overseas and tried to get it running again after nearly 5 years in storage. I checked every sensor and every wire going to the ECU ( IAW 15RC . C8 ) and the instrument panel connector. Everything looks to be OK but it won't start the fuel pump and won't fire the coils, needles go up to full scale, then down, all indicator lights are dead except the high beam indicator.
Any clues? Is there an immobilizer that could cause this?
Any help would be appreciated,
