Went out to start the bike on the weekend and wouldnt start and throwing code 651 4. Manual says injector 1 issue. Searched on the forum here and couldnt really see any fixes. Some say it was battery issue with low voltage, but this guy has an odyssey 925 with a tender on it all the time. Battery is only 6 months old, so wouldnt think it would be that but will check the voltages. Others say to check the wiring harness from the injector to the ECM for shorts or breaks. Will check that out. The way we got it to start was to switch relays from the EFI to the fan. Possible defective relay? I think it was just coincidence, but hopefully that was it. Anything else we should be looking for?
Thanks
