Hello
I have an '06 Nevada 750 Classic that refuses to start, taken multiple steps to diagnose and fix the problem but running out of ideas. The bike turns over strongly with a new battery and will cough on each cylinder individually with easy start sprayed into the injector hole.
Sounds like a fuel issue right? Using GuzziDiag and by cranking I have isolated each injector individually and both are fully operational. I have spark and fuel on both cylinders. Air then seems obvious but using an e cig with the tank off I can see it is pulling air in to some degree through the intake.
I am struggling as the bike has air, fuel and spark!
Crank sensor is functional as they all fire with the starter rotating, I am thinking possibly a fuel pressure issue or an air pressure issue. Have not removed airbox to check for blockages as I didn't think it likely. When it fired on easy start the injector was out (able to draw air) which I realise does not help diagnosing whether air or fuel.
Thought I would post here in case there is something I am missing? I am not experienced with Guzzis but built a few Ducatis in the past with similar electrics.
To confuse things further (possibly a red herring) left plug was dry when removed despite the left injector visibly firing while out of the bike for testing.
Background: Bike has sat for 10 years, was put away due to same issue as now. Fuel has been changed, fully charged car battery connected.
I would appreciate any advice that can be given, thank you.
