Thanks again for the help 12V at the fuel pump connector did nothing so removed the engine and found the negative terminal on the pump snapped off, re spliced that and it’s running perfect now I cannot believe how frustrating the engine is to remove, I’m an aeronautical engineer and would prefer changing an RB211 than an Ossa 300 engine…..!!

Thanks Konrad that’s a fantastic website, fair enough the AAA won’t run the fuel pump but when should the pump run? When I’m kicking the bike over with the fuel pipe removed from the injector I get no fuel coming out?

Hi all I’ve just picked up an Ossa 300 - 2014. It’s got the updated battery pack helper on the front end with the AAA battery it’s got a decent spark, but it just won’t start i cannot hear the fuel pump at all, ive cleaned the injector and tested that with a 9V battery and it’s working fine when are you meant to hear the pump prime? First/second kick? I have the fuel line off the injector and nothing is coming out
