Cheers Simmo
Have removed the R17 relay that others have advised and the ticking is still there.
Have found another R17 and tried that but it is still the same.
Unfortunately the other R17 relay is from a second hand fusebox so I suppose that could have been a bad one.

Try 16? If one is ticking you may be able to actually feel it?.  Try 11 ?

I have narrowed it down. the ticking stops when I remove relay R21 which according to the chart is the ignition lock. Have tried a different relay of the same type in slot R21 and the ticking starts.
Unsure if this is connected to why the car keeps cutting out after a few minutes then won't start for an hour or so.

Finally got through to a mate who has an OBD hoping he can check it tomorrow after work.

Mate turned up with his MODIS OBD computer couldn't get the car to start but we have found the following:
P0141 Heated O2 sensor heater circuit malfunction Bank1 sensor 2
P1124 Throttle position sensor out of self test range
and finally when we turned the engine over the system gave an engine speed of 0 RPM. All the other figures shown moved when ignition key was turned and starter motor was running engine speed stayed a firm 0.
From this my mate says next thing to look at is a new Crank Position Sensor which from his description of what it does sounds a good idea.
Are the other two faults critical as well?
Have looked at the page here to see how to replace the crank sensor:
http://www.fordscorpio.co.uk/manual/engineman/cosworth/24vCKP.pdf
and it looks like it is at the front by the belts. Is this right?
Cheers Everyone.

Got the same thing but after changing over the PCV it's just water (condense from blowby exhausts being recirc'ed to inlet). If you look at the little filter pad where the recirc'd exhaust comes into the air box it'll probably be horrible with a consistency of salad cream from soaked oil/water mixture.
My scan shows nothing obvious (though wondering about pre cat sensors) but car still runs fine - it's just that the emissions are now high. Might be a leak in the vacuum system but nothing obvious so might just change tubing and see if things improve.
BTW - has anyone tested the vacuum pull from the PCV in a 24V? That is, with engine hot and running pull out the PCV and put thumb/finger over end to feel how strong the 'suck' is. It's barely noticeable on mine though the 'valve' appears to be working (and rattles as it should).

I have been looking for a crankshaft sensor like my mate advised. The instructions above mention a lower and upper bolt but all the pictures of the crankshaft sensors for sale that I can find have just one hole is this right?

As you don’t have a code relating to the crank sensor I don’t see any reason to suspect that over anything else. The TPS however is critical in that it conveys to the engine management the position of the throttle - since you have a code for it you should sort that out first.
You could try a battery disconnect to reset the TPS value (make sure you have your radio code), whilst not as severe a problem as yours this gives an indication of the importance of the TPS:

They are 2 bolt. I might have a spare if you dont have any luck finding one. It sounds like your looking at the cam sensor, thats a 1 bolt

Cheers for the feedback
Battery had been recharged and replaced just before we tested the car (have to take batery out to recharge as car is on the road). Would that have reset the sensors before the test?
I think the reason my friend suggested the crankshaft sensor was that he seemed to believe if that gave a 0 reading for rpm while turning the engine over the car computer would simply shut everything down to prevent damage elsewhere.

Just fitted another crank sensor (thanks Matt) ran lovely for about half an hour then I turned engine off thinking all eas OK. Just got back in the car turned the engine on fine and realised I had not put spare tyre back in the boot. Turned engine off put wheel back in boot. Turned engine and it won't start now. It is trying but not firing up.

Cheers Matt
Fuel cut off is pressed all the way in.
Just a thought does anyone know if it is possible to bypass the cutoff switch in order to rule out a problem there?

Friend came down plugged his obd machine in and there was a 0 rpm reading again. He got under car and cut the outer sleeve back on the wires. Both the wires were missing their insulation. Seperated the wires by the connector to the crank sensor and car started and ran fine for a while and showed decent rpm on his computer. Then died. Wouldn't start until he wiggled wires. Looking at that next. Just have to find how far back we need to go to find healthy insulation. So har found bad insulation as far as under the top waterpipe to radiator.
