Hi guys recently my fuel gauge has stopped working. when i turn the ignition on my fuel gauge goes from half a tank all the way upto the full mark and it had half a tank of petrol in. Now when i turn ignition off it then goese down to about half way and goes spazz. It goes up and down a couple of times like very little movement. I just don't know how much fuel i have left in it now. What in the world can i do

please help me. Hope you all understand what i mean by this. thanks

i'm having similar problem, but mine can have plenty fuel in, but still just sit with amber light on as if it's nearly empty. Caused me a problem last week when I thought I had enough fuel, but didn't and car just stalled on me (luckily not on a busy road)

hi mate had problem with my fuel guage today and fixed it

other people on here had same problem as me in the past but no one ever posted a deffinate fix how ever from breakdown recovery experience the only real time ur sender is at fault is when the pump thats attached to it gives up other than its your guage not reading the sender unit properly change your guage for one that u know works fines as i did today its fixed milage is abit on new clocks like but its reet my fault was switch ignition on fuel guage goes from top to bottom 3 times then sits dead on bottom without fuel light on ??? giving you false protense's into believeing the guage is working because its moving....no not true

I totally disagree that sender units cannot cause problems like this. Sender units have a resistive track that wears out particularly when around the quarter tank and less mark - changed many for fuel content misreads.

Erractic behaviour that you are experiencing is likely to be the gauge. In the case where the gauge always indicates empty a simple test is to earth the wire from the sender unit. The gauge should then shoot up to full proving that the gauge is working.

If you disconnect the sender unit and the gauge is still misreading (should drop to empty) then you have found the likely problem of a gauge playing up. It could also be a wiring issue but very very unlikely (not impossible though).

Hope this helps....

also after trawling through forums lots of saxos suffer from the problem of the guage sticking at half or 3 quarters full this also the guage to be at fault as my mates VTS did this around 5 month back....i do agree with buggerfeet but im basing my opinion on my eccounters with saxo's and never finder a sender to be at fault....sometimes the wiring that plugs into top or mostly the guage to be at fault REGARDS dan
