Fuel gauge problems

[waggy2114 0]

Can anyone out there HELP. I have a 91 G60 and when i bought it the fuel gauge was not working at all. I changed the fuel pump to see if there was a problem there and still no movement. I then aquired a set of clocks which were sold as "working" once i put these on there was some movement on the fuel needle hooray. Now no matter how much fuel i put in the gauge does not go above a quarter, any ideas anyone?? :confused4: :confused4:

If you have fitted some replacement clocks it is more likely to be the sender in the tank.

Do you have any ideas on a fix for this then can you just replace the sender.

You replaced the pump - new VDO pumps use a different sender to the Pierburg original - did you change this too or manage to get an old style pump?

 

Are the clocks VDO or Motometre?

The clocks are VDO and i did replace the pump with one from a vr6 but the old pump was still working i just changed it to see if it made a difference to my gauge.

Ok, if you want to test it then these are the readings you should get across the 2 pins at the plug for the sender, the other 2 wires are the live and earth to the pump (thicker gauge)

 

Full 35 Ohms

Half 90

Empty 285

 

Worth checking these and then maybe cleaning the tracks of the little pcb that the gauge gets its signal from.

Hi, sorry for threadjacking, just got a quick question..

I replaced my old pump with a Bosch one, but the sender unit didn't fit. Will the VDO-sender fit the Bosch pump? :confused4:

Not too sure if its a 4 pin plug it should do.

Hi Wormy, not sure i'm afraid mate... maybe worth calling Bosch up, the tech guys in the autoparts dept are usually pretty good.

 

The VDO one is wider than the original where it slots in I think...

Sorted i think i had the pump sat facing the wrong way round and the float could not fully move .

Thanks for eyeryones help and advice.
