Fuel Pump Relay? Or something more traumatic...

It's a miracle?
It's a miracle?
Originally, after the car was dead, we removed the gas line and cranked the car. We got almost no gas flow during cranking. This lead to the family friend's conclusion about the fuel pump. That's when I tried the bypass of fuel relay test...during which the fuel pump was fine. So, after replacing the relay, there was no difference in the behavior of the car so I figured I would be taking it to the shop, especially since I still couldn't access the engine module.
Well, a few days ago, I tried again to test the control module. Once again, I could not connect to the engine module. All seemed lost.
But was it a stroke of fate or something else that made me forget to turn the key off? Today the battery was found completely dead, of course, with the key in the ON position.
That sucked, but we jumped the car to start charging the batt. While we charged the battery we decided to take the hose off the gas line one more time. I was thinking I could prove the pump worked for sure by bypassing and then checking the flow. But before I bother to bypass it, I just cranked it as it was. Strangely enough, there was plenty of gas flow on cranking. I didn't predict that would happen since I didn't think anything had actually been fixed. Hooked the gas line back up and the car fired right up.
Now I sure do wish that I had tried to start the car before opening the fuel line again so I could know more about why it started working. Could be the air bubble theory? Could it be some kid of electrical cure caused by leaving the car on for 3 days? Now, when I turn the key on for the car, I can hear the throttle moving in addition to the funny clicking sound I heard before. And also, now, I can finally connect to my engine module.
So it seems I am spared by the Audi gods, for now. I just wish I knew what the heck caused this and what the heck fixed it so that this post could be more useful for the next person that might have this happen.
Happy but confused.
