I shot some ether into the engine and it chugged a bit so I do not believe its an electrical problem. I also tried jump starting the battery - still nothing. I think it is a fuel delivery problem - probably air in the gas line preventing fuel from getting to the injections. How could I make sure that the fuel line in clear and that fuel is getting into the engine?
From the test you made you definitely have a fuel delivery problem. You need to check, in that order, Fuel pump, fuel lines for blockage, injector pulse the the injectors themselves. Plugging the car to VCDS could easily identify fuel pump and injector problems.

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.

Check this site for any Audi codes. This is a problem with the air that it injected into the exhaust system to help burn any uncombusted fuel. Check the air pump located in front of the pass front wheel on the bottom of the engine. It is pretty easy to find. The air pump has a suction hose that goes to the air filter housing so that it has filtered (clean) air, follow the hose

I think I can help you. I just did this on mine yesterday because my clock runs a few minutes fast each month. It was somewhere bizarre - sorry I'm not near the car to be more clear. I think I picked Sound, Settings and for some odd reason, it was there, rather than in Car, Settings. NOOO - it was in Tuning - click the AM/FM button, then Settings. I've only had it for a few months, but you'd think I'd have that one figured out due to re-setting it.

You have to bleed the system, most likely air, or you blew the fuel pump fuse !
