Never do resistance readings with current flowing through the 
wire.  Resistance is measured with the key off, voltage with key on.

readings the sending unit is good. If this fails check the ground to 
your instrument cluster. There should be 12 volts to the other side 
of the gauge.

Hey guys was just wondering if there is a electrial test to tell if a fuel
guage was faulty or if it is the sending unit. It worked fine last fall and
just got the car out and its no working. I cleaned the ground wire and metal
on the body it attaches to and still dont work   Thanks in advance   Finally
spring is here in Mich sure was a LONG winterthanks   Steve
