razgs300 Posted January 7, 2010 Share Posted January 7, 2010 Hi guys, can somebody help me why is the fuel gauge not working? At first, I thought that the fuel is very low but after refuelling the car, the needle just won't go up and the low fuel warning light stay on. I just realised that the the car almost stall when I stop and the idling is very low. Could it be due to fuel pump dying? Quote Link to comment Share on other sites More sharing options...
razgs300 Posted January 8, 2010 Author Share Posted January 8, 2010 So, nobody knows what is the main reason for the fuel gauge failure? Quote Link to comment Share on other sites More sharing options...
TigerFish Posted January 8, 2010 Share Posted January 8, 2010 Whish i could help mate, but I have a mk1, not a mk2. Other than checking the fuses, it would only leave the sender and the wiring, or the dash guage itself of course. On the mk1, there is no fuse specifically for the guage, only a 7.5A "Panel" fuse that supplies the whole dash. Again, on the mk1, you can check the resistance on pins 2 and 3 of the sender unit, you should see readings of approx 3 ohms at full fuel, and 110 ohms at empty.

Thanks for the feedback mate :) Yes, If im not mistaken, theres no fuse specifically for the gauge. Im thinking this is due to the faulty fuel pressure or the floating mechanism in the fuel tank Quote Link to comment Share on other sites More sharing options...
TigerFish Posted January 8, 2010 Share Posted January 8, 2010 Maybe the diagnostics for the mk1 will help as far as resistence across the terminals of your sender. I think the sender is reasonably easy to reach from the boot behind the trim panel. Sounds like it may be stuck. Quote Link to comment Share on other sites More sharing options...
razgs300 Posted January 19, 2010 Author Share Posted January 19, 2010 Is it possible that the floating mechanism become stuct at the bottom? Is the thing uses a sender or just a simple mechanic? Quote Link to comment Share on other sites More sharing options...
The Swede Posted January 20, 2010 Share Posted January 20, 2010 I had this problem on our IS300. There was actually no issue with the gauge in the tank. A low Battery charge (we mainly drive short distances with that car) turned out to be the culprit. I put the car on a charger for a night and the problem got solved.

razgs300 Posted January 21, 2010 Author Share Posted January 21, 2010 Well Swede, I tried replacing the Battery with a new one just now, it just didn't work. I guess the sender or the floating mechanism is faulty :( Quote Link to comment Share on other sites More sharing options...
muntisk Posted June 21, 2010 Share Posted June 21, 2010 Hi Did you fix problem with fuel gauge? Its seems that i have same problem. Mine at the beginning was flouting up and down, but now it stuck in down position :( TNX Hi guys, can somebody help me why is the fuel gauge not working?

Could probably due to faulty sender unit or the floater stuck at the bottom of the tank. Have you fix yours? Quote Link to comment Share on other sites More sharing options...
GOLO Posted November 6, 2010 Share Posted November 6, 2010 Hi I seem to recall reading that the fuel filler cap needs to be screwed on tight, at least 3 clicks! or the car may not start. It might be worth checking! try searching the site. Just clutching at straws. Quote Link to comment Share on other sites More sharing options...
razgs300 Posted November 26, 2010 Author Share Posted November 26, 2010 Its fixed already :) Turned out to be faulty sub fuel sender unit. Bought a new one and now the fuel gauge is workiing :) Quote Link to comment Share on other sites More sharing options...
