Hi otif,

if you have spark the car should start and run/sputter when introducing fuel (starter fluid). If that doesn't work go back to the basics:
- get a good new DME relay or jumper both stages in the DME relay socket
- check DME gets power (vibrating ICV with key in ON)
- check that fuel pump comes on when cranking
- verify you have spark (inline tester)
- verify you have fuel (NOD light and check fuel pressure in rail)

If no spark and no fuel the first thing are the flywheel sensors, Ohm them out. Next, it could be the DME. If only fuel or only spark pulses this is more likely the DME. Also if sparks are intermittent that is a typical failure of the DME.

Good luck,
Ingo
