Temp gauge doesn't work

Like the title says, my temp gauge doesn't work. It will move with the rest of the gauges at start-up, but doesn't read after that. I replaced the coolant temp sensor, now what?

Here is the location of the sending unit for the gauge, it should be the one in the back on the intake. Here is a flow chart for it. Use DVM if you have one to check resistance.
