My fuel gauge started playing up last week or so.
No matter how full the tank was, the top bar of the LCD display would not 'light up'.
I thought that it might be a 'sticky' float, but didn't want to empty the tank, pull out the pump and twiddle with the float just to find that it could not be fixed and have to put it all back again.
Was bored at lunch time so thought I'd fiddle with the fuel level sender connector, just for fun. I pulled the connector off, it looked fine, no corrosion or other damage - looked well sealed against water ingress - anyway I blew into the contacts and replaced it - Yippeee the top fuel bar now 'lights up'.
Must have been a high resistance contact - slow-mo light contach corrosion over 4 years and 41,000 miles?????
So before you run off to the dealer with a faulty fuel gauge - take a look at the connector.
Note to self - must measure the resistance of the fuel sender mechanism, when full and empty, for future reference.
