Fuel guage wont read

My fuel guage will not move off of empty. I never know how much fuel I have in my truck. What causes the guage to not read?

    It must be really frustrating not knowing how much fuel is in your truck! My Subaru has a similar problem, except the gauge plummets to empty after it hits halfway, even though I can keep driving for a couple of hundred miles. I'm not sure about you, but I think I'll take my Subaru to a mechanic to see if they can fix the gauge. http://www.danics.com.au/

Click on the link, this site has some info. I sometimes use a couple of resistors, one represents empty and the other represents full, use the resistor between the two terminals for sending unit, key on, see if gage reacts properly to each resistor, if it does, the problem is the sending unit in the gas tank or the electrical connector. It the gage still doesn't react proper, either wiring circuit problem or maybe the gage is faulty.

The wire to the sender in the fuel tank is shorted. If it was open or disconnected it would read full.

Ajkill is right. I had the same problem with the fuel light always being on and the guage read empty no matter how much fuel is in the tank. I had to have the fuel level sensor in the tank replaced. This is something that they have to drop the tank for. It was about $400 with the part and labor at the dealership.

this problem is caused by a defective fuel gauge sending unit in the fuel tank.

You will have to have the dealer reset the security light to restart vehicle.Check all engine and chassie grounds because this is where the lighting would exit the vehicle.It sounds like a ground burnt through.

SOURCE: fuel guage moving all over 2006 chevy trailblazer

I had this problem as well. Took it to the garage and it was a $700 bill the part alone was $440 they had to drop the gas tank - and since then it's not been working right. The fan clutch went a week later another $700 bill. Picked it up and it was still making the same sound - garage replaced another sensor without charging me--picked it up and three days later the service engine light came on. Back to garage and another $80 part was needed under the hood. All this with just 52,500 miles and I keep it well maintained. Not a happy camper at all! Holding my breath but it's been only two days so far so good.

SOURCE: fuel guage & water guage are not working

The gas tank sending unit has a float on it to register the amount of gas in the tank. The float is probably faulty which will cause erratic readings and is a fairly common issue with some GM units. Replacement of the sending unit should resolve that issue. As far as the coolant temperature gauge, it could be a faulty temperature sending unit or a thermostat that is stuck open or someone removed the thermostat. This will cause the engine to never reach operating temperature which in turn makes the engine run rich and can clog cat. converters and destroy some sensors.

Fuel guage does not work


The most common cause of an inop fuel gauge is the fuel level sender inside the gas tank is defective, this causes the gauge to read empty or just move a little when filled in some cases depending on where the break in the resistor that the float moves is located.

GAS GAGE WANT STOP READING EMPTY WHEN GAS IS IN IT


To confirm if the fault is with the Rheostat float within the fuel tank or the fuel guage in the dashbboard, you can remove the wiring to the fuel tank float. If the guage reading changes- to full- then the guage is good and the fault can be a jammed rheostat which can be removed from the tank and replaced after draining the tank. The guage can be tested on the outside with a ground wiring to the plate of the fittings and as the float is moved the guage must show a change in reading. if not the voltage must be measured to confirm the working of the guage.

2006 ENVOY fuel guage reads empty after fill up. What is the cause and how to rectify?


Usually I find there are two common causes for this problem. If the gauge goes to empty after a fill up but then starts to work and be fairly accurate as the fuel level in the tank drops then it's often the fuel level sending unit which is attached to the fuel pump module inside the tank. I have seen some guages go bad also [actually the servo motor that runs the gauge] but usually the gauge will stick in one spot and rarely move or go to either end of the scale and stick there. A good shop should be able to determine the cause of your problem pretty quickly. Hope this helps and good luck!

Grand prix gas gauge not working


should be a grey wire going to the top of fuel tank connects to fuel guage / when the guage in the tank reads grounded it shows full , no ground it shows empty. if you ground that grey wire and the guage jumps to full then faulty guage if nothing maybe bad ground on the tank itself. the guages are a reostat like a tyco race car gun the more it moves the more it grounds .. good luck

Gas Gauge not reading correctly


The most likely culprit is the sending unit in the tank. They are relatively easy to change, as long as you don't have much fuel in the tank. It's a mechanical unit that has a float that raises and lowers with the fuel level, however with age, the floats can develop leaks and no longer float, of the electronic portion of the unit can go bad and not register the proper level. They are replaced and an entire unit, so it doesn't matter which happened, you will need to change the fuel tank sending unit.

Fuel guage reads 1/4 at all times even when full. How do I repair


1.If the needle on the guage is stuck. you can try tapping the guage to see if the needle moves or turn the ignition on and off a few times to see if you can get it to move. If the guage drops to empty when you turn off the ignition you know that its not the guage. (note that the guage does not drop to zero when ignition is off with all cars of this age).

2. The problem could be with the sensor in the fuel tank itself. Rocking the vehicle up and down from the rear (you will need help doing this) may free the sensor level indicator ball in the tank.

You likely need a new fuel sending unit (it's in the trunk, and is what drives the gauge).
