Could be a sending unit, but it is most likely a wiring problem, either broken or corroded, from the sending unit to the gauge cluster (Ground should be pink/orange(or just find any good ground to use, and the signal wire should be yellow/white) these colors are based off a 2004 MGM diagram. The output signal should vary between .5-4.5v if operating correctly, if I remember correctly.
