some functions you will need:

pawn Код:

GetVehicleVelocity
GetVehicleModel(GetPlayerVehicleID(playerid) );
GetVehicleHealth
TextDrawCreator ( this is not function) ..search for Zamaroht's Textdraw to make a textdraw, and make a box..after use it in combination with what i said..and what you learning and yeah a nice Fuel system

new Fuel = 100;
forward FuelLost(vehicleid);
public FuelLost(vehicleid)
{
       Fuel --;
      if(Fuel == 0)
     {
              for(new i = 0;i != MAX_PLAYERS;i++)
               {
                         RemovePlayerFromVehicle(i);
                }
     }
     return 1;
}

OnPlayerEnterVehicle(playerid,vehicleid,isspasanger)
{
        SetTimerEx("FuelLost", 3000, true, "d", vehicleid);
       return 1;
}
