1967 250SE cold start problem
 

Hi guys,

My issue is there is no power to the cold start valve.

Here are some questions::confused:

1- Can someone describe the way the cold start valve system work?
2- Is there a "engine running signal" on these cars?
3- Does the cold start valve only get power when the engine is running or does it get power when the engine is cold and the ignition on?
I feel like the CSV should only run when the engine is cold and is running. Correct?
4- Does anyone have the wiring schematic for the CSV?

I much appreciate all the help.
Much regards
