View Full Version : Toyota Landcruiser fuel gauge problem

All of a sudden my fuel gauge is reading about 1/2 what it should. Full
tank shows half, half a tank shows 1/4 etc.
Any ideas where the problem lies or how to find the problem please.
Sender in fuel tank?
Gauge on dashboard?
Something between fuel tank & dashboard?

This is an old Landcruiser, 1990, and one of the last 24 volt versions as
far as I know.

Many thanks

Sounds like the system has two senders and one is permanently reading
empty either through being jammed or a damaged connection. See if you
can find them and measure their resistance (with the loom disconnected.)
Whichever one reads 0ohm or open circuit should be the duffer (ie, the
working one will have some moderate resistance.)

Where are we going and why am I in this handbasket?

probably a leaking float half full of fuel on the sender unit.
