Yako, if the anti-theft system (EWS II) is activiated, the car will not crank over. NOTHING will happen when you turn the key. If your engine is turning over, then the EWS is almost certainly bypassed.

It is beginning to sound like your DME may be bad. If the CPS is okay and the main relay is okay, then you should be getting spark. If you jump the fuel pump relay terminals and the pump runs, then (especially if you put in a new fuel pump relay) that, in combination with not having a spark, also leans towards a bad DME

The Haynes manual is woefully insufficient for diagnosing a no-start situation. Search this forum or Google for the Bentley manual. There is a link where you can download a copy in PDF format. Section 120 is where it sounds like you need to focus.

Most problems are usually something simple !
