fuel gauge?

Can somebody tell me if they've had trouble with their fuel gauge? It started when it got below half it would just go to empty. Now I filled up today and it only went to half. Are there relays that control it or could it just be the float? I don't know how they work. Thanks

im not 100% sure on how the tj fuel system works but it does sound like it would be the sending unit.

Sounds like a float problem to me.

Check the connector before you drop the tank.

Fairly common in 97+ TJ's, XJ's and ZJ's, they might have fixed it by 2000. The sender is part of the fuel pump, I've been told you can get just the sender from the dealer and replace that but have not seen it first hand. You have to drop the tank and pull the pump to get at it.

While I had my tank out to replace the pump, I cut a hole in the floor right above it, then screwed a plate over it, and sealed it with duct tape.

It was a good thing too - the new pump was defective! With the plate it was an easy job the 2nd time.

He He - I carefully measured. Then put the tank in place, found I'd measured wrong, close, but no banana - so I had to enlarge the hole a bit.

After it lined up OK, then I made the cover plate to go over it.

6 sheet metal screws hold the cover on, Duct tape seals the crack from dust and air.

One of those stupid little things they should have done at the factory, friend of mine had a dodge daytona in the 80's, that had the hole and plate already there.

I have the same issue with my 97'. After a 1/2 tank, the guage drops terribly quick. If I remember correctly I thought I read that it was a defect and was then re-called. I plan to start looking it up cuz I need to get it fixed.

Toyota did think of this. The 4Runners have a factory access plate underneath the Pass rear seat. Fuel pump changes in under an hour.

I know for a fact it was a recall for the 97XJ, unfortunately my 98XJ was not covered even though it was built in Sept of 97 and was a 98 model year that I bought in December of 97. Ticked me off, never went or will go back to a dealer after that.

Well I think I got it fixed. A buddy of mine dropped my tank and replaced a part in there that cost about $50.00-$60.00. It had something to do with how it read how much fuel was in there by ohms. He showed me where it was worn out. Right now it's working perfectly. It's the float part of it, if that helps.
