You either have another mod/resource that uses or disables the F6 key, or you need to restart your server/client. Sometimes it randomly stops working even after reloading the resource. A full server and client restart is required in that case. I can’t figure out why this happens so I can’t fix it atm.
Last update was about 3 months ago, haven’t had that issue myself nor has it been reported since. Are you sure it’s this script that’s not working?
All i know is fivem updated on my end a couple of days ago and thats when it started. I have not added any new scripts. It tries to shut the engine off but fires right back up. May just be a coincidence on the update, im not sure.
It’s strange, sometimes I’m having this issue as well but most of the time I don’t… Not sure what’s causing it… (besides not being in a complete stop before shutting down the engine. If the car is moving while turning the engine off it’ll just start back up)
