I thought at first I could help because a fuel gauge showing full all the time is usually caused by a short or the fuel gauge wire grounded. However after all of the efforts it sounds like anything from a sticking float in the tank to wiring problems. You will need to use a meter and trace wires from the tank up then inside to the tank as far as you can go internally. Did you have the furl pump out when you changed the sender? Did you do anything with the float?
Hi, all wire is good just that the fuel gauge don't read right. i replaced the brand new gauge from dash and from tank (the sender) and wire check now. what happen? i don't know :( anyway the whole dash don't work now. millege, rpm, gas gauge. heat, all that was down. lol .. the fuse was good too.
Is that instrument cluster digital? If it is you may need to have it rebuilt. Or, if you don't care about keeping the mileage accurate you can get a used one at a salvage yard.

Hi! Fuel sensors have fuse. Have you tried checking on the fusebox for fuel gauge fuse? It may be faulty or blown thats why its not reading right. Try to check it and replace if necessary. HOpe this helps and have a good one!
Can you try to detach the instrumental panel and check if the connectors on the display is burned? The connectors may be fried thats why you dont have any display. Once you checked and found out that they are fried I would suggest that you get a replacement on the junkyard. It will be much cheaper than buying a new one.

Hi, I have a 99 4runner 3.4L. it is all about the fuel gate shown that is full tank all the time even my fuel is low. Now i replaced a sender located in the fuel tank. ( seem like it doesn't work). so, i replaced a new curcuit plate No. 3. ( the fuel gate reader). it seem like it is working to me but since the gas was very low, i have put $20 into it, than the gate doesn't move up at all. I used a 12 volts put thru the wires from the sender unit just to see if the gate reader will move up and yes it is moving up to hafe of the tank!!! now i let go the 12volts out the gate reader fall down to emty and i test it again 3 times, but my original millege it is disappear and the fuel gate reader is still emty. what should i do? please help

i already check it at first time but no fuse was broken. they all ok. that is why it make me more worry about. this fuel sender has 3 line one of them is ground and other two is power. i been check all that already. now my main point is about the millege is disappear how can i restore them?.
ok.. i didn't check it yet but i'll do that, just wondering i have power prob 3 tools that i used and check it i point the top tip into one of each line to check what is ground and power so i got the power line and the other line wasn't do anything so i input 12 volts in that line i saw a level gate on datsh is moing up to the right position and the display was showing zero. any moment? please...
actually i already fix the problem just that i want to know if you guys know something but let me tell you what is the problem. the problem is the all about a circuit is bad. the circuit is at behide the millege dash. thank you anyway.
