If the door lock line was plugged in the engine bay than it shouldn't be affecting the shut-off. Your symptoms aren't a lack of vacuum, it's a lack of the valve bleeding the vacuum off after the engine shuts down.
You can also try shutting the car off with the STOP lever on the engine. This will bypass the vac shut down. If the car starts up normally then the valve is bad.
