HELP!! My Audi 100 won't start!

It sounds like you have checked most of the usual suspects.
You should be able to hear the fuel pump when it is running, so I would check the fuel pump relay.
I had trouble with mine (T44)... kept cutting out when coasting. Resolved by resoldering some dodgy joints in it.
You can take the relay out and replace with a jumper wire (across the 2 big terminals) to get the pump to run. (Only for testing - do not leave it like this without the engine running).
