Default Cbr954rr no start despite everything looking good

Hey there everyone, i just bought a fire blade that has been sitting for around or over a year and got it to run (ish). When using starting fluid it fires up perfectly and revs, however when not using it it doesn't even start. I've rebuilt the fuel pump, cleaned the tank, previous owner put in new injectors, i did new vacuum lines, and i got it to start once while checking the vacuum line on the FPR and it had no leaks, battery is also brand new. I got codes 1,2,9,11,15,35 and went through the manuals procedure of checking resistance and voltages for codes 1,2,9, and 15 and all were fine, haven't checked code 11 and code 35 has that little module to supposedly remove the servos.



I genuinely have no clue what could be the issue now that all the sensors should be "good", and the fuel system should also be "good", i could maybe try checking to see if the injectors got clogged in-between the previous owner replacing them trying to fix this same issue and me starting the bike now.



Any and all help is appreciated, much thanks to everyone involved.
