Hey..!!!

Is the '00 A6 4.2l has a relay between the ingnition and starter? if so, wich one is that? I turn the key to crank the engine but nothing's happening. There is power in the battery, so i don't think is that, the car has only 3k miles on it, so i don't think is the starter. These models does not have imobilizer. Power goes in to the ignition, when i turn the key comes out like 13v. So it's not the ignition either...
Any idea...
