To change the headlights on a 2000 Toyota Echo, first, open the hood and locate the headlight assembly. Remove the screws or clips securing the assembly, then gently pull it forward to access the back. Disconnect the wiring harness from the old bulb, twist the bulb socket counterclockwise to remove the old bulb, and replace it with a new one, making sure it’s securely in place. Finally, reattach the headlight assembly and test the new bulb.
When you first turn your key (two clicks I believe) before the car starts, all the lights should come on just to let you know they work. If the light doesn't come on even then, you need to replace the light in the dash. If it does come on for the test, but not after you start the car when its cold, it could indicate a problem with a temperature sensor (which should be replaced).

Check the basics first (air filter, belts, plugs) but the most likely cause is dirty throttle body or mass airflow sensor. You can easily clean both on your own although MAF sensor should be replaced after 100,000 miles. Throttle body can be cleaned with Seafoam penetrating lubricant and a toothbrush or wire brush. You may also want to test the alternator (Toyota calls it the generator)
To replace the starter relay in a 2000 Toyota Echo, first, locate the relay in the fuse box, which is usually found under the dashboard or in the engine compartment. Remove the cover of the fuse box and identify the starter relay, typically labeled on the diagram inside the cover. Use a flathead screwdriver or your fingers to gently pull out the old relay and then insert the new relay into the same slot. Finally, replace the fuse box cover and test the vehicle to ensure the new relay is functioning properly.
Echo repeats whatever you put on the command line.echo This is a testwill echo to the screen:This is a test

Test the relay and the temperature sensor.
