gas gauge doesnt work

it always stays on E and the light is on, how do i fix this. i know it works it was full when we got it, ran it to E then filled up and it didnt go up. now im worried that im going to run out of gas in the middle of no where.

On the 91 or the 94?

oh my bad the 94'

Ok, and only the fuel gauge is wrong?

Haynes manual has a fairly simplistic diagram for the instruments. Power runs to fuse panel, then red/blue wire to gauges. Just a guess that there is a printed circuit board just like my 90. Power to one side of the gauge then tan wire runs to fuel sender in tank. Diagram indicates there is a ground wire, black, at the tank.

If the other gauges are Ok, then check the black ground at the tank. If that ground is Ok then try wiggling the connectors/wiring harness in back of the instrument cluster.

Good luck.

PS--I have a 90, and when the gauge reads empty the sending unit has low resistance, 1 ohm, and higher resistance, 88 ohm, when full. There is a change on the later models, and I don't know the cut date, and the sending unit resistance is reversed, i.e., low resistance means full and high resistance means empty.

ok i'll try that

i have the same problem in my 92 tell me if you find a soloution

hmm it was too cold and wet to crawl under my jeep, but the gauge was working the tank before this one. there might be a possibility it might have got stuck or something
