[_Outbreak_]

Under OnPlayerEnterVehicle you need to set the engine to 0, so it isn't running.

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
     new engine, lights, alarm, doors, bonnet, boot, objective;
     GetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
     
     if(engine)
     {
          SetVehicleParamsEx(vehicleid, 0, lights, alarm, doors, bonnet, boot, objective;// the 0 is setting te engine to off
     }
     return 1;
}

That should make the other code work under OnPlayerStateChange
