mamboman 0 Posted June 19, 2008 Looking for some advice on a faulty fuel gauge. I have just replaced the ignition coil and ECU unit and discovered that my fuel gauge is reading half a tank when in fact the tank is full. The MPG reading is also way low. Any suggestions ?

mamboman 0 Posted June 23, 2008 In response to my own topic - managed to sort out the MPG reading, but the fuel gauge is still not happy. Is the fuel measured from within the tank or is there a sensor I could replace in the engine bay..somewhere? Please help! Cheers all. Quote Share this post Link to post Share on other sites
blue95 0 Posted June 23, 2008 AFAIK it's in the fuel tank. Unscrew the big cap and pull out the pump. Should see the gauge has a metal arm coming off it with a float. You can't replace the gauge, its part of the unit, assembely. You can re-uue the pump though. Quote Share this post Link to post Share on other sites
waynos 0 Posted June 23, 2008 how did you fix the mpg reading then? Quote Share this post Link to post Share on other sites
SamRS 0 Posted June 23, 2008 on my g60 the mpg guage is reading high 60's low 70's at times, clearly not right, any idea what could be causing it to over read? Quote Share this post Link to post Share on other sites
mamboman 0 Posted June 24, 2008 Right - I'll have a go a the pump/float assembly then. I had the MPG trip computer on setting 2! (Idiot). Second time. Thanks all. Quote Share this post Link to post Share on other sites
mamboman 0 Posted June 26, 2008 Aghh!! After replacing the ECU and the ignition coil all was well for 1 week apart from this fuel gauge issue - which seem to sort itself out. Filled up yesterday and after 125miles it just cut out...in rush hour traffic. Managed to start it again but cut out a few miles down the road. The fuel gauge registers fuel but it cut out like there was no fuel in the tank. I picked up 5 litres of 99 octane poured it in and it started again. Took it home. Turned off the engine and it wouldn't start again. Tried it this morning, started first time. The starter motor is brand new and seems to working fine but the engine will not fire for some reason. Strange smell coming through the vents, bit of white smoke out back to. Had enough now - can't afford to spend anymore on the old girl. £2500 in two years is enough I think. Any ideas?
