Mine is like this :

PHP код:

public OnVehicleSpawn(vehicleid)
{
    SetVehiclePos(vehicleid, PlayerVehicle[vehicleid][vX], PlayerVehicle[vehicleid][vY], PlayerVehicle[vehicleid][vZ]);
    SetVehicleZAngle(vehicleid, PlayerVehicle[vehicleid][vZr]);
    SetVehicleHealth(vehicleid, PlayerVehicle[vehicleid][vHealth]);
    return 1;
} 


PHP код:

CMD:respawnall(playerid,params[])
{
    if(PlayerInfo[playerid][pAdminlvl] >= 2)
    {
        for(new i = GetVehiclePoolSize(); i > 0; i--)
        {
            SetVehicleToRespawn(i);
        }
        SendClientMessageToAll(red, "[SYSTEM] "blancU"All vehicle respawned");
        aAlert("/respawnall", playerid);
        return 1;
    }
    else return SendClientMessage(playerid, red, "You are not allowed to use this command");
} 


I think problem comes from DestroyVehicle(id);
You can't respawn a vehicle which get destroyed.
