Question 2003 Lincoln Navigator Fuel Tank/Miles to Empty Reading PROB


I went to a shop today to get an amplifier 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 fuel tank 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

What does your fuel GAUGE read????.........Those two functions are usually tied together...........What did your stereo installer tap into for power and ground???.........Possibly fuel pump, sending unit circuits???

Alot of newer cars can get damaged while attempting to jumpstart or "boost" the battery. Everything in the car needs to be shut off first, or else you risk damaging electronics.

Whoever did this install, needs to fix the problem. It might just need a reset by disconnecting the battery then reattching it.
