Question about 2000 Ford Expedition
Replace the regulator that you are talking about which is probably the starter solenoid or also called the starter relay by Ford. They will go bad and only cost about $30 from a dealer or auto parts store, so it is relatively cheap to replace. I actually just replaced one on our family owned Ford F-350 last year which is a 2000 and had the same symptoms, really simple to replace for anyone. Let me know how this turns out.

The "regulator" you are referring to I believe is the anti-theft module. When you tap on the module you are apparently allowing a temporary connection to the module that is allowing the module to see the key code, validating the key and allowing you to start the vehicle.
I would first pull lightly on the connector at the anti-theft module and see if it pulls off. If it does, the connector was not locked and was causing the problem. I the connector was locked, disconnect the connector and inspect the connector terminals. Look for corrosion, either green or gray colored powder. Look and the terminals and make sure they all look identical in the connector, same height and width.
If all checks OK, the module may need to be replaced. Unfortunately you will have to take the vehicle to the dealer for installation and configuration of the new module.
Below I have attached the starter wiring diagram for you Expedition for you to review.

TAP ON WHAT REGULATOR? THIS SOUNDS LIKE THE KEY SENSOR MIGHT BE DEFECTIVE IN THE IGNITION LOCK CYLINDER, DOES IT DO THIS WITH BOTH KEYS? 1ST THING TO DO IS TRY THAT, THIS MAY BE A DEFECTIVE KEY AS WELL. I AM A 25 YEAR VETERAN FORD DEALER TECH SO KNOW THIS TRUCK WELL.
