Fuel gauge

[SuperDad]

My 1996 Bronco has this problem too. The gauge moves between empty and 1/4 tank. I just watch my miles and try to fill it up everytime I get 300 on a tank of gas.

But I would like to fix this problem.

yo Dad!

here ya go; Testing & Connector Pin-Outs in 92-96 Bronco;

"... gauge that pegs past empty indicates a short to ground (pinched to the frame, body, or dash supports) on the Y/W wire, OR a sunk float. See diagram in Steve's SM site Hot Link; look at Connector C441 for problems. Yon can test a lot there for the sender..

Look for the Connector @

And inspect wiring at Fuel Pump/Level Sender on top of tank (tuff to do; some cut out floor pan for this as well as pump/sender replacemnt)

btw, da (pump and fuel level sender share a ground) At Rear cross member so, since pump works, dwell on sender wiring

also;

Sender Range: Full = 160 Ohms; Empty = 16 Ohms;

gauge that pegs past full indicates an open circuit (broken wire; unplugged connector; corroded terminal; burned sender) on the Y/W wire.

gauge anywhere in between that doesn't move indicates an open circuit (blown fuse; corroded terminal) on the power (battery) side of the gauge OR a bad instrument cluster ground at C251 pin 9.

The terminals of C251 & C250 are known to corrode & lose contact. Polish both the connector pins AND the film circuit pads with brown paper or a pink eraser. The larger version of C441(WPT454) was used until '93. The level sender can usually be disassembled & repaired by bending the wiper arm inside the plastic housing to apply slightly more force...

Sorry to drag up a old thread but I am trying to figure this out. My fuel gauge on my 1995 is past empty and never moves. I see that if it doesnt move it would be a open circuit, but if past E check y/w wire?

Correcto!

Instead of dropping the tank, consider a Cut-out Panel for Fuel Pump/Level Sender Replacement see the LINKs for many @ http://www.broncolinks.com/index.php?index=616

esp; Cut-out Panel Fabrication for Fuel Pump/Level Sender Replacement in an 83

my 85 having fuel problem also temperature gauge is miss up. so the fuel gauge reads under 1/8 goes up a little with i put about 30 dollars in it. the temp does nothing.

Just wanted to ask if you guys know where I should start....my 1988 Bronco II XLT gas gauge is pegged past Empty, my wipers dont work and the radio last power all within a few days of each other. First I noticed that the gas gauge would register in between full and empty if I filled up the tank, then after driving a few miles, it would drop past empty and the radio would lose power. this would happen intermittently for a few weeks but them the gas gauge stopped working and remains lower than empty even with a full tank, wipers dont work and radio will not turn on.

Any Idea where I should start looking for the fix?
