Hello am new to this forum and hopefully looking to resolve the issue I have with my 300 gts , turn the bike on fuel pump primes as normal , immobiliser comes on once then goes out as expected as per normal. But all power to the start button is completely dead , engine will not turn over , if starter relay is bridged engine will spin over but won't start . I have checked all the connections on the entire wiring loom and all are fine , brake lights are working , also tried bridging kill switch and start switch and still isn't working . Have been over the bike for a few days and physically can't find anything wrong with it , battery is good as I borrowed it from my other Vespa . It's a 2016 abs 300 with digital clocks , will appreciate any help thank you .

According to the wiring diagram the one thing common to both ability to turn starter and fire the ignition is the ECU.
