Fuel help!!

[Sande]

Hey, i try to edit this fuel script. Can someone do a function like, if fuel is 0%. Its turn engine off alltime.

  
local carFuel = {}; 
local gasStations = {}; 
local gasStationsBlip = {}; 
local gasStationsMarkers = {}; 
addEventHandler("onResourceStart", getResourceRootElement(getThisResource()), 
    function() 
        local xml = xmlLoadFile("carData.xml"); 
        local xmlNodes = xmlNodeGetChildren(xml); 
        for i,node in ipairs(xmlNodes) do 
           carFuel[tonumber(xmlNodeGetAttribute(node,'id'))] = tonumber(xmlNodeGetAttribute(node,'fuel')); 
        end 
        xmlUnloadFile(xml); 
        local xml = xmlLoadFile("garageData.xml"); 
        local xmlNodes = xmlNodeGetChildren(xml); 
        for i,node in ipairs(xmlNodes) do 
            local name = xmlNodeGetAttribute(node,'name'); 
            local x = tonumber(xmlNodeGetAttribute(node,'x')); 
            local y = tonumber(xmlNodeGetAttribute(node,'y')); 
            local z = tonumber(xmlNodeGetAttribute(node,'z')); 
            gasStationsBlip[name] = createBlip(x,y,z,51,0,0,0,0,0,0,450); 
            local moreKids = xmlNodeGetChildren(node); 
            gasStationsMarkers[name] = {}; 
            for i,v in ipairs(moreKids) do 
                local mx = tonumber(xmlNodeGetAttribute(v,'x'));

It already does that, so, what's the problem with it?
