Help with why gas-gauge is not working?

[4.3LXJ]

Crist, the way it works is that when you turn on the key, power goes directly to the gauge. Then through it to the sending unit. The unit then acts as a variable resistor, changing as the fuel level changes. The power goes from there to ground. If the gauge doesn't work at all, then probably the power is not getting to the sending unit. If it only works a little or incorrectly, then it is usually a ground issue

Poked around a bit today... No progress. Trip to the local mechanic for help.
