Passenger side is HVAC and Cruise.....I am confused....is that one minute 55 seconds.....whatever you capped on the passenger side...that has nothing to do with the secondary vacuum system.
It sounds like you are saying when you turn the key on (engine off) your vacuum pump is on for 1 second and off for 6 seconds which means you have vacuum leaks but are still functional on secondaries.
It would require you to start at the pump vacuum lines and work rearward to and under the plenum checking to see where that vacuum leak is located. Just unplug connectors and hold finger over side of connection coming from the Vacuum Pump. If Vacuum Pump quits cycling, the leak is beyond that point. If Vacuum Pump continues to cycle, leak is between that point and the Vacuum Pump.

I appears that both of you have functional Secondaries which you can very easily check with engine off and key on........
