It's correct that there is 12V to the CSV as long as the ignition
switch is on.  The circuit gets completed by the Thermo-Time Switch
which shunts it to ground when it decides to fire the CSV.  Otherwise
the TTS is open circuit.

The hot start pulse relay is not found on every CIS car.  Many don't
have it.
