Methods above do not work at 1.1 version.
If came here like me, try this method to write normal engine system:

 

mp.events.add("playerEnterVehicle", (vehicle, seat) => {
    mp.game.vehicle.defaultEngineBehaviour = false; // stop starts engine when player press 'W' or enter vehicle(because we using it in event)
    mp.players.local.setConfigFlag(429, true); // stop problems with animations
});
