Fuel gauge stuck on empty after filling up.

[gjscott]

We were empty with the low fuel light on, we filled up, the low fuel light went off but the gauge needle remains on empty . 
Any ideas?

1. Try giving the instrument fascia a tap.
2. Fuel level sensor is stuck right down, or has a bad rheostat track.

Update: The fuel gauge was showing full yesterday morning, but the car has now travelled about 30 miles singe and it hasn’t moved. 
Watch this space.

When both our Citigo's have full tanks (not sure when that will be possible again!) it does take a while before the needle starts dropping.

The gauge now appears to be working again. I wait with baited breath to see if it will stick on empty again.

Bear in mind these gauges are not precision things - just there to give you an indication of fuel level.Better to know what mpg the car does for your driving ,and work it in conjunction with what you see on the gauge........

Sure! But OP appeared to have a gauge that had become binary, which is not right.

IMHO, the sender arm was stuck, as sometimes happens.

Binary means two of....I think you mean binding.  The gauge in my car does not move off full until at least 50 miles have been travelled,so not a true indication of correct fuel level.If the float in the tank was as low as it could get in the OP car ,no surprise it was suck down .Once saw a petrol tanker driver years back ,throw a cigarette paper (rolled his own!) into the ground petrol discharge hole whilst unloading..............but he did not light the fag.........

First. The fuel gauge was showing empty, after it had be filled up.

Second. 

 

Only two positions, but now started working again and needle is going down.

Thanks, AG Falco

Two positions - full or empty, seems to justify my "binary" quip!

If it is a regualr occurance, you'll need to pull out the sender and have a fettle...

(it is very unlikely to be the dash gauge these days).
