pawn Код:

#define CAR_AMOUNT 1000

Max cars is 700, why 1000?

2.

pawn Код:

new Text:vehht;
TextDrawDestroy(Text:vehht);
//some if's...
new vhealth[256];
new Float:vehhealth;
GetVehicleHealth(vehid, vehhealth);
format(vhealth, sizeof(vhealth), "~p~Vehicle info ~n~~r~Health:~w~ %.0f~n~~g~Fuel:~w~ %d%",vehhealth,Gas[vehid]);
vehht = TextDrawCreate(500, 415, vhealth);

You're destroying the textdraw, and creating a new every second? Try with TextDrawSetString.

3.

pawn Код:

NoFuel[playerid] = 1;

NoFuel assigned to playerid? IMO vehicleid would be much better.

4.

pawn Код:

if(strcmp(cmdtext, "/exitveh", true) == 0)
    {
    if(NoFuel[playerid] == 1)
    {
    RemovePlayerFromVehicle(playerid);
    TogglePlayerControllable(playerid, 1);
    }
    }

no "NoFuel[playerid] = 0;" ?
