Yes.

Pretty sure its the same as the 2000 Toyota echo, see related link.
If the A/C is not working on a 2000 Toyota Echo, the pump may need to be recharged. It is also possible that the belt for this is broken or the thermostat is sticking.
Mine is a Toyota echo 2000 sedan. It does about 12 to 15 KMPL per 1 petrol litre.
there are no 2000 yaris that would be an echo
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.
