T in your vacuum gauge between the shutoff on the fuel injection pump an that hose you pulled off. Start the engine and let it run a bit and have someone shut off the Ignition and see what vacuum you are getting.
If you are not getting sufficient vacuum to shut off the Engine then it could be the vacuum valve, the position of the hoses if you had the hoses off.
On mine the line going to the vacuum shutoff on the fuel injection pump is brown with a blue stripe. That line goes to the bottom nipple on the vacuum shutoff valve on the steering locum lock.
The solid brown line goes from the top of the the vacuum shutoff valve on the steering locum lock to a Y connector with one leg of the Y going to the main vacuum line and the other leg of the Y going to the vacuum valve on the fuel injection pump that is used on models with automatic transmissions.
When you shut of the the vacuum shutoff valve on the steering locum lock vacuum bleeds out of it; if it held vacuum you would not be able to start the Engine.
