Hi Gameboy, welcome to the bad engine compartment loom club. Here's my experience of 2009:
http://www.fordscorpio.co.uk/cgi-bin/yabb/YaBB.pl?board=Problems;action= display;num=1235484612;start=0#0
It looks like it is the engine compartment loom section between firewll and front of the engine compartment playing up.
It comes and goes; maddening. It is a combination og age, bad loom isolation, heat off the exhaust shield and moist inducing electrical gremlins.
Mind you: your loom's wiring's 13 years old. Though after 1996 the isolation material was improved still odd leak currents will influence Scorpio's circuits and functioning, making lights flicker, fans go on and off, drain your vattery and sound your alarm.
Have a look at these pics if they look familiar:

Only way of curing these symptoms is replacing this loom's section wire by wire or finding a complete, good used one (I was lucky to find one in Germany).
There was an RHD loom on offer on eBay the other day; see recent post: http://www.fordscorpio.co.uk/cgi-bin/yabb/YaBB.pl?board=Problems;action= display;num=1280820811

Dont replace the loom yet Dave! 
can you start it in neutral?
I'd say its the PASSENGER side fusebox at fault, (Ignition lights and heated screen work off this fusebox) check the bottom of it for water ingress

Hi everybody thanks for all the great info have checked the fuse box on near side and found to be swimming in water which ties up with a massive rain storm we had a few weeks ago, pos could be looking for another box if this one dosnt come back to life.

passenger side one can recover from water ingress Dave, it might be ok once it dries out.
Do you have a battery cover fitted?

The passenger side one doesnt suffer as badly as the drivers side one Ray as the connectors and the actual fusebox are suspended above the water.
The drivers side however is different as the water sits in the circuit boards and works its way in.
Hopefully it will dry out ok

Highlander, on an RHD Scorpio is the driver's side junctionbox the one with the big multiplug (that needs to be seated properly)?
Where does the battery sit on an RHD, left or right?
Curious,
Ray

The dirvers side fusebox IS the one with the large multi-plug and the battery on a RHD is on the passenger,nearside.

Dave, it looks like you are having the electrical gremlins to visit you.
Most Cossies now - yes, I was a victim too - suffer from infamous engine compartment loom trouble: brittle isolation of the wires and strands, touching and cross-infecting each other, disturbing, resetting, malfunctioning components. Heat, moist all work against you.
All Cossies are now over 12 years old... Sometimes even shorting battery Plus against other wires and making them go up in smoke... happened to me.
What also happened in my case is a typical, less known EEC-V habit.
When you disconnect any of the engine loom compartment wires/connectors, running to and fro the the EEC-V * while the battery is connected * the EEC-V will "freeze", or "hang-up" for about 24 hours.
You might have even discovered this faulty wire, repaired it and still no ignition joy.
This is because the EEC-V is permanently connected through the battery PLus over the 6 injectors' positive side. In other words there is always 12V on the sensitive EEC-V ports.
When you start fiddling with wires and connectors, a static charge builds up in the EEC-V, which takes about 24 hours to leak away. Starting fine the next day! Maddening.
Golden rule: when working on the engine compartment loom and the engine "fuel cut off" loom * always, always * disconnect the negative battery pole. For instance when you disconnect the EDIS or coilpack, or take off the ABS connector etc.
Once done, reconnect. Otherwise you will face a 24 hr hang-up of the EEC-V which bejaves like an upset PATS: immobilised. Discovered this the hard way...
Please Check with your garage whether they did any of these fixes with connected battery - most do.

I'm not convinced the wiring is at fault here.
Have you actually seen any signs of wiring problems Dave?
As far as i'm aware we have had a wet passenger side fusebox?
What are the actual problems now Dave?

Hi the garage has dismantled the pat unit found to be burnt out, they seem to have by passed the engine start section, My question is if I replace the pat/immobiliser do I have to change key and lock as well all matched or immobiliser only.

Dave
