Dang, I hate posting from the office. Got in a hurry and messed that up. In my case the sending unit went bad, causing the gauge to peg at all times.
Using an Ohm meter (or Ohm scale on a DMM) attach one lead to the post on the sender and the other lead to the block. If the sender is bad you'll show no resistance. If the sender checks out, double check your harness for an open line.
