Non Starting Espace

2001 Renault Espace 2.2 dci Non Starter after breakdown:

Engine: G9T 710

Bits I know! :
No power to electric fuel pump.
No relays clicking after turning on Ignition
Diesel Pre-Heat fuse blows when turning on ignition. (may be separate problem)
Engine fires with easy start.
I have disconnected the glow plugs and glow plug relay and it still blows.
All grey relays in engine compartment test Ok with relay tester (I know that one of
them is fuel pump relay, although not sure which one)
Battery OK
Oil Level OK
I fitted a new Crank Sensor (I had to tap it in quite hard so may have damaged it :-( )
I replaced the casing on the key and had to transfer contents to the new one. It has
been working fine I also have an untouched key that used to start the car before
but doesn't work either.
Immobiliser lights go out as they should.

Can Clip does not connect.

Code reader (Foxwell NT600) reads ABS & Airbag computers but not Engine computer
(reads engine ok on my 1999 2.2 dt)

It would reall help if i could find out which relay does what in engine compartment and a
pinout plan of the ECU.

I have found a secondhand ECU with the same part number on EBay would this be a straight swap
or would it need programming?

Any help would be much appreciated. Thanks in advance!
