I am getting a steady temp of -32 on the GP2 input.
Shouldn't I have a volt reading on the w/r 5v. power wire?

So there are a few sensors you can use for coolant temperature. Which one are you using? And which sensor type do you have selected under the GP2 setup?

I am using the 100409-000 temp sensor on type 3 setting.
Should I get a volt reading off of the +5v. wire?? I don't now.

Yes, you should be seeing 5V on that wire.
If you're seeing -32, by the way, that means that as far as the EMS is concerned, it doesn't even think the sensor is connected.
Much more often than not, issue like this are wiring and not problems with the unit.
In this case, once you have the 5V sorted out, make sure you have it connected to the circuit via a 1k resistor as shown in the diagram for that sensor installation.
