There are more things than that going on. Check for spark - if you are receiving spark, then it is NOT a EWS issue. If you have no spark, then its EWS. In rare cases I have read that the DME can loose the EWS key which is an easy fix if you have the cables and software. I ended up getting the cables and software, along with INPA and it's been a blessing as I was able to confirm the fuel pump will turn on via DME and pulse all injectors. It's possible you have a cam or crank position sensor issue.

Check the wiring diagrams as well. Sitting beside the fuel pump relay is the DME relay. It will provide signal power to the relay (the DME provides ground). Power is always on if I remember right.

One thing you can try is to bypass the fuel pump relay with a jumper to turn on the fuel pump and then try to start the car. This will confirm two things - 1) the fuel pump is definitely receiving power at the pump, and 2) if it starts, you have a problem within the fuel pump circuit.
