a large number of free electrons are present in metals why is there no current in absence of an electric field across it

In a metal, large number of free electrons are found. These electrons are in constant random motion that means they are moving here and there. Thus, current generated in one direction is cancelled out by current generated in opposite direction by these randomly moving electrons. so, net current in a metal is zero.
