If pulling off the Brown striped line solved your issue then it is likely the shutoff valve on the steering colum lock is not working correctly. It may need to be cleaned or replaced.

Also be sure to note the positon of the Vacuum hoses on it as it matters where they go.

Note that if you get a new Steering Colum Lock and you buy it as an assembly you get a new Steering Columl Lock+the Vacuum Shutoff Valve+ a new Ignition Switch.
