I'm pretty sure there will be no fuel pump on the 20,000 toyota echo. Also pretty sure there won't be a 20,000 toyota echo. But if you want to check the fuel pump on a 2000 toyota echo, see related links and questions.

You did not mention the symptoms you are experiencing. But see the related link for how to check the fuel pump. To check the filter, you have to remove it.
The primary reason for hesitation on acceleration from stop on a 2000 Toyota Echo is a dirty fuel system. This can include clogged fuel injectors or a dirty fuel filter.
The reset switch for the fuel pump on a Toyota Echo depends on the year it was made. It is either in the trunk, under the carpet, or it is under the passenger side dash.
The purpose of an air flow sensor in ANY car is to measure the air coming into the intake of the engine and communicate this to the ECU (engine control unit) so the EFI (electronic fuel injection) knows how much fuel to deliver to the combustion chamber.
