My scenario:
#1. Gas gauge works, reads F when talk is full, but reads R probably when tank is half empty.
#2. EDU appears to work, but like gauge, will read 0 miles left even though I have many more left to go.
#3. My low warning fuel light seems to work just fine; it lighted up the other day when I had between 2-3 gallons of gas left.
It all started acting weired right after a 2 week cold spell where I didn't drive the car. Upon starting, my EDU seemed to go nuts, all the lights lighting up. I reset it, and it appeared ok.
Perhaps the resistance element in the sender broke due to the cold weather...
Here is what Ari wrote in April in response to my question on the matter (thanks Ari):
A. "What does the Miles To Empty on the EDU say? Does it show low numbers? Do you get a Low Fuel light?
The Fuel gauge is driven by the EDU, and the EDU reads the fuel sender. If the gauge reads empty but the EDU says you have 200 miles to empty, then worry about the gauge. But I doubt that, as gauges tend to be pretty good.
If the EDU is giving you 10 miles to empty when you know you've still got 12 gallons in the tank, then it's probably the sender. It's probably a break in the resistance element in the sender. About the only reasonable solution is to replace the sender."
B. (From Michael S. back in Feb.): "The EDU gets the fuel level signal from the tank sender and also feeds that signal to the fuel gauge through a jumper terminal, ie it doesn't exactly pass through the EDU but both terminals receive the exact same signal from the tank sender."
So there you have it. I drive with mine broken for now and go by the odometer. I'd like to fix the sender myself it is a reasonable DIY job.
