@Calum well i have an update, im not expert electrician by no means but i know some stuff, started taking everything off and tested bunch of stuff, first of all coil is gone, it test OL on every combination of terminals possible, so good i ordered genuine one, i just dont get why it still sparks. Power valve on servo has been messed with the cables are way too long and look like they have been wraped around te servo rotor or whatever but i cannot get bottom part out near engine as one screw is stripped and i didnt have time to deal with that, so i will be ordering new cables probably when i open bottom part as its possible its been pinned. I have one question and im not sure if thats normal or what, i have 7ohm resistance on battery terminals, when key is ON and if on beeper it beeps, when key is off it doesnt beep and resistance is OL..
