Pull the fuel pump fuse No. 17.
Remove the coil pack, flip it over, place 5 used plugs (any type) in the coil to plug boots and ground the plug threads to the cam cover. Have a friend try to start the engine. Look for spark(s) from the plugs. No spark = POS or coil issue or blown ECU fuse.
How to remove the coil pack:

If you have no CPS codes, and the fuel pump works when you test it and you have spark, then it could be a faulty J17 fuel pump relay. Read more in the link.<ul><li><a href="https://forums.audiworld.com/s4s6/msgs/149827.phtml">https://forums.audiworld.com/s4s6/msgs/149827.phtml</a</li></ul>

It could be the problem and will need replacement anyway. Do NOT get an aftermarket one. Buy only from a dealer. See link.<ul><li><a href="https://forums.audiworld.com/s4s6/msgs/204624.phtml">https://forums.audiworld.com/s4s6/msgs/204624.phtml</a</li></ul>

Even if you didn't get a 2113 blink code, if everything else is good when you tested them, then the likely culprit is the CPS.
