I have a few more things to add.
1. I have check for voltage at the cold start valve connector during cranking and do not see any voltage.
2. I have replace the thermo time switch with a new one.
3. I have checked if the cold start valve is putting out any fuel and it is not.
4. I have OHMed out the wires running from the cold start vale to the thermo time switch and they are good.
5. The Haynes manual(not a good manual but I got it with the car) I have, talks about the frequency valve relay controlling
the thermo-time switch, but says nothing of its location.
6. I am testing these things at 30F with a cold engine so the thermo-time switch and cold start valve should work.
7. I have received a few responses that I should here the frequency valve making noise. I hear the idle stablization valve
runing when I turn on the key.(If I am not mistaken, it looks like a little fuel pump on top of the valve cover
So it appears that my cold starting curcuit is not working. My guess it is some relay or connector.
I will be thankful for any info!
P.S. Thanks for all the help this brake light question. It appears that some other wire is broken.
