Thanks for the clarification, I'll check the RCM for relay operating tomorrow morning (its dark and cold here in London!).
If my TCS relay is not operating on Run/On, would that cause a no start ?

Would love someone else check what they see on the pink/red wire on A2, I see 12v with ignition at On/Run and Start.

I hope you are correct and pulsing on and off is not correct, would make more sense if the enable signal to the PM was simply high/low

Just looked at the TCS wiring, seems the TCS relay gets 12v from ignition switch via a diode to operate the relay and the contact switches 12v to the SLA.

 

Tighed1,
Yes, just confirmed, Ign switch to On/Run - ECM and TCS relays hold operated and the Fuel Pump operates and then releases.
Have ordered a Pulse Module.
Do you know what voltage or condition should be present on Pulse Module pin 1B when ign switch is in Crank position ?
I'm seeing 12v.

Good news, I've fixed it ! Car starts OK. Whilst twiddling my thumbs waiting for the Pulse Module to be delivered via eBay, I thought I'd take another look at the RCM.
As I said before, the RCM looked perfect, all solder joints were clean and no sign of burning etc. I had already re-soldered the 3 points indicated in other posts and continuity tested all tracks, coils and contacts OK, so I decided to carefully re-solder every joint, plugged it and hey presto !
Thanks for your advice along the way.

In fact it was post no. 6. On reviewing the posts this morning, it prompted me to give it a go. I must admit, I was subconsciously initially looking for something obvious like a burnt or broken track, or an obvious powdery dry joint but the RCM looked factory fresh. Just goes to show, what looks good on the surface may not be underneath !
Big thanks to PIzzaGuy

 

Traction control relay should also be engaged.
Manually close it then see what happens when you try to start the car.

 

DJ, look at posts 23 and 24
