I have a 1999 Ford Taurus and gas gauge does not work. I have replaced the sending unit in the tank and the gauge on the dash but still nothing. Is there fuse links anywhere??? Thanks

Remove the fuel tank and replace the fuel level sending unit is what will be needed is my guess.

Nine times out of ten, it is the sending unit in the tank that is the problem. To check, use a sort jumper wire to ground the gas gauge wire to the frame while watching the gauge needle on the dash, with the key in on position.

Find the gas tank electrical connector by the tank. Pull it apart, and on the harness side of the connector, locate the wire going to the sending unit. I don't know what color it is, but the fuel pump wire is a pink wire with black stripe and there is a black wire for the ground. The other wire should be for the dash gauge's sending unit. Have a helper turn the key to on and watch the gas gauge for any perceptible movement while you use the jumper wire, insert one end into the terminal for the gauge's sending unit wire (this is on the harness side of the connector, not the gas tank side), and touch the other end to the car frame-you are grounding it. If the dash gauge is good, the needle should move a lot, usually will move more than half way, one way or the other. So if it does, you know the dash gauge is good, and the problem is in the sending unit.

If it is the sending unit, it is quite a job to drop the tank, pull it out from under the car, then pull the fuel pump and sending unit out. You might be fighting a lot of rust on an '89-get some penetrating oil. And look for the removal procedure in a repair manual. It's not terribly difficult if you are handy with tools...and like to get dirty. Those hoses on the tank have been stuck on there a long time. Good luck.

It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

Fuel level sending unit. that is the most common problem with these vehicles that cause the gauge to quit working

You remove the fuel tank and change the sending unit
or live with it the way it is

Wes, try checking your float in your tank, or check the sending unit.

If you are referring to the gas gauge, It is one of 3 choices or a combination of them. 1 A bad float in your tank. 2 A faulty sending unit May be in tank or by fuel pump. and 3 loose connection from these to yor dash gauge. Good Luck

Hi, sounds like you have checked everything properly and you have a bad tank sender, current when checked with test lamp should pulsate.I suggest replace fuel tank sender.

You are going to have to replace the fuel guage sending unit in the fuel tank, nothing else will cause this problem that this 20 year Ford dealer tech has seen.

there is a sending unit in the tank this has probably clogged or wore out it has a filter on it, with gas debries this will make your guages stop working correctly

replace sending unit by dropping tank with gas out of tank and then pull out sending unit replace with new one
