Another fuel gauge issue

10th January 2014, 19:39

Right,I've spent the last hour reading through other fuel gauge related issues on here and its rife with the saxo....holy fuck

Anyway,I've experienced an issue maybe two or three times since owning the saxo where the fuel gauge sticks at a certain level,on the odd occasion the speedo and rev counter can stick,but on one occasion the speedo and rev counter worked fine and it was the fuel light which gave it away.

The light came on when there was just under half a tank and I knew then it was at it again,so I did the usual and disconnected the battery.......problem solved.

But I now think there is a new problem.....

I had the fuel level at just over the half when I decided to fill right up.I filled up until the fuel nozzle shut off and when I got in the car to drive off I noticed the gauge was at roughly 3/4.....maybe slightly above

My initial thought was WTF

But then I thought maybe theres an issue where it doesn't register any higher and when the level drops to actually that level,it will start dropping with it.The fuel gauge needle still drops to zero when the ignition is off,so unlike the other issue its different in that sense.

Now I'm hoping its as above,and if it is....what would it be?could it be the sender is starting to fail in such a way that it won't register a level above the 3/4 mark?I'm not sure if this is relevant or not but I've never had the fuel level above 3/4 on the saxo since owning it.........so its maybe been this way for a while.

Or it may be that it sticks at the 3/4 mark but I won't know until I do a bit more miles......

I've read up about doing that earth wire trick but if it does what I'm hoping it will do then I can live with that......and if its a goosed sender then I'll happily replace that.

Any thoughts

Maybe a few years worth of gunk left in the tank and clogging the sensor? Just a thought as I may be wrong. The needle really gets funny when you park up or down a slope.

The gauge started working as normal when the fuel level reduced down.......

I decided to fill back up again when it was just above the half mark and the exact same thing has happened.

Filled up until the pump cut out and the gauge is at just above 3/4

Seems strange

Got a issue with mine on my build as well -

full tank shows half way.
half tank shows empty with fuel light on.

Moves down ok when ignition off.

Here's a pic of where it goes to when I fill to the brim

That seems more fucked up than mine

When my fuel level drops to actually ^^^^^ that point the gauge reduces down with it......why the needle would go to that point and no further is beyond me.
