2003 Lincoln Navigator Fuel Tank/Miles to Empty Reading on the Dash PROBLEM!

[maniac0788]

hello,

I went to a shop today to get an [COLOR=blue! important][COLOR=blue! important]amplifier[/color][/color] set up on my 2003 lincoln navigator. I had about 125 miles in my fuel tank untill it was empty. While installing the ampifier the guy wanted to test the radio and the car wouldn't start for him twice and the car had to be boosted back up. After my amplifier was installed and when I was about to leave the shop it said that I had 345 miles in my [COLOR=blue! important][COLOR=blue! important]fuel [COLOR=blue! important]tank[/color][/color][/color] when I only had 125 before I entered the shop. What could be the problem? Why is the computer incorrectly reading the amount of gas left in my fuel tank? Will this problem fix itself? Is there a way that I can reset the fuel indicator(Miles to Empty)?


Thanks in advance and any help with this will be greatly appreciated

Sounds like an anomaly due to the wire connections not done right when tested.
You'll see a similar problem if you ever fuel the car with the engine running.

It will right itself after a few ignition cycles, and the averages will get more precise after a few refills.
