Cranks, won't start
 

So, bought a 98 A4 Quatro 2.8L as a winter car this week. Wipers weren't moving so followed instructions at:

While trying to get wiper mechanism out, I unplugged the relay on left in ECU box under the hood.

Now the car won't start. The engine turns....won't fire. Any ideas?

Rolling rock is good beer. Secondly, test the relay with a multimeter to see if it's still good.

Well, checked out the relay. It appears to be good. When testing, I hear the click in the relay and then my multimeter is showing proper resistance. Other ideas?

I figured it out.....it was me. When pulling the ECU box forward, the wiring harness for the fuel relay snapped out of socket. In retracing every step....that's when I found it. Thanks for the earlier reply.

Good to know it was something simple! That would've sucked if it was something expensive and/or time consuming.
