The cold start valve is normally located on the intake manifold or somewhere close to that. It has a fuel line and an electrical connector, and looks alot like a fuel Injector. But they normally only operate below 0° from what I found. And only for 12 seconds. If it has problems running until warm i would also check the coolant temp sensor.

Try to find a Chiltons or Haynes manual for your car. They are invaluable tools for working on vehicles.
I put some Marvel Mystery oil in the gas, don't know what it does but the car starts fine now.
