Hi,have just had 80k service on my 05 echo 1.3 and now the alleged new fuel pump makes a constant whirring whizzing sound which to say the least is annoying.Having been driving for 30 years and owned numerous cars i have never heard this eminating from any other car.My wife took back to toyota and they made her look stupid telling her its because its a new fuel pump, thats what they do,but from what im reading its not what they do ,can anyone shed any light on this problem,,,thanks, phil..
