Light blinking,gas gauage dosnt work on 2002 toyota echo, just filled it up didnt fix it

The first thing to do for your dash lights is to verify the fuses, if ok check your lights dimmer next. Sometimes, dimmers fail to provide good contact due to wear or poor filament contact. Otherwise, there is a poor connection somewhere.
Usually, a rapidly blinking turn signal is due to a burnt bulb on the side in question or a bad ground connection either in the front or the back of the vehicle. Turn the left signal on and check if front and back turn lights are on and working if one doesn't work check the bulb. If it is poorly lit and not blinking check the socket and ground connection.
Hope this helps you!

run the fault codes to find the problem . Guessing and changing items just costs money and becomes frustrating. With the engine light on it could be more serious than plugs and coil

Have you looked at your oil fill cap? It should tell you what type of oil to use. I have a 2002 Echo 1.5l and mine says 5w-30. I also have a 2005 Pontiac Vibe and it has a Toyota engine 1.8l that is slightly bigger than the 1.5lmotor in our Echo and it also takes 5w-30. I think you would be safe using 5w-30; however, I would look at your oil fill cap.

find out what code it is showing and repair

problem with the purge canister it's under the car on the rear that is connected to the filling hoses big problem with those cars. i just installed a new tank new hoses but put a second hand purge unit and my 2005 echo is spitting back and hard to fill. good luck

how do you know the gasoline is bad? I have seen vehicles stand for several years and then start okay.Siphoning out through the filler cap is usually fairly hard to do as most cars today have a device in the neck of a tank to stop theft. If you really wanted to remove all the gas I would suggest using a hose of no more than half an inch in diameter. This may just fit down through the filler neck, you would have to play with it to be able to get it all the way to the bottom.

sorry to say, this is typical of the echo, after a couple yrs, the fill tube begins collapsing, not allowing enuff fuel flow,, your alternatives are to replacew the fill tubes, or to just pump fuel very slowly.

blower switch is your fan knob on dash. resistors are located under pass side dash next to blower motor. on alot of cars the blower will work on high speed and not the lower ones- this is a tell tale way to tell the resistor is no good. if this happens again after replacing resistor- ive seen the blower motor shorting out causing the resistor to go bad- then you would have to replace both.(this usually dosnt happen, most often the resistor alone fixes the problem..
