Landyfan, I understand your frustrations, "been there, done that" myself.
Please humour me on this next suggestion, you may have done this, but I have re-read your posts and cannot be sure. The following was the "eureka moment" for my CRD troubles.
Pull the ASD relay from it's socket. Place a jumper between 30 and 87 in the socket. This by-passes the ASD relay. Does it turn over and start? I know you said the ASD relay clicks, but I could find no verification of continuity through the contacts in your posts. if it does start, you have a faulty ASD relay. This was exactly my issue. The contacts were burned in the ASD relay. Replacement cured the issue.
Good luck from the other side of the pond!
That certainly is a good test,
but keep in mind, if it spins over and starts using the jumpered pins method you suggested, this could also be telling you the ECM is not satisfied with one of the many inputs it receives at to activate (ground/energize) the ASD relay.
Hopefully he has already checked the main power feed fuse to the ASD relay along with the several fuses that get power once the ASD relay is energized.
With the ASD relay unplugged and testing it's connections with a 12v test light or multimeter, he should have 12v at terminals 30 & 86 (key on or off) and a ground at terminal 85 (key on).
He could also simply try swapping the ASD relay with one of the other relays of the same size and see if it spins over and starts. This would test the relay itself if the ECM is providing the ground for the relay.
Low & High speed fan relays, or the blower motor relay.
