Earth found, pump running, still no sparks!
Going to try to find/check the crankshaft and camshaft sensors as in the previous post, as well as the throttle position one.
I have found a few loose wires so there may be one that I have missed.....

OK, was checking the sensors and found a plug that was not quite fully clicked into place. Now have sparks!!!!!
Got to make dinner before full start attempt though...

Ok, tried - no joy but fuel leaking from somewhere over garage floor! Not from pump to engine or vice versa. Have to leave it to ventilate overnight
before investigating.

There is a rubber pipe coming from the fuel pressure regulator that is not connected to anything.
There is also a pipe (narrower bore, covered in a red cloth) that comes from the throttle body - on my car, it has been cut and nothing to connect
to.
There is also a 'spare' connection on the throttle body that looks like a pipe should connect to it.
Having looked at a friends car a while ago, I connected the red cloth pipe to the regulator - that pipe now smells of fuel and i think was pouring
fuel into the inlet.
Can anyone help with which goes where (it is in an awful place to see, let alone photo!)

The fuel has a pressurised supply through the white fittings and a low pressure return to the tank through a red fitting. Are you using the Fiesta
fuel pump?
There is also a cannister purge in the emmisions systems - this is blocked off on mine but does leave an ECU error code.
I don't have/remember a red cloth pipe.

There's a bunch of air pipe fittings on the inlet manifold. One of these connects to the fuel pressure regulator and the others should all be
blocked off as shown below.

Sounds like your nearly there! We WILL need a video!

Found a slightly better pic of the blocked off air pipes.
 
Vacuum pipes
And of the fuel tank/pump connections:

Well, my photo is even worse!
You can see the pipe that would go to the servo - that will be blocked off. (Top left pipe)
To the right of that is the one that goes to the red cloth pipe (not connected to anything) (Top right)
Underneath that is the line to the EGR thingy (bottom right)
To the left of that is the unconnected pipe (bottom left)
I looked at a friends car, which had the same configuration as yours, and therefore connected the top right pipe to the fuel pressure regulator - the
pipe from the regulator was bigger and the red cloth pipe fitted inside it.
My regulator looks slightly different to yours. My fuel pump etc. is standard.
Naive question: I assume that the fuel pressure feed is a suction feed to the regulator? It smells like fuel was coming through it!
Thanks once again for the help and support and don't worry, my son is primed with the camcorder for the glorious moment!!!

Ok, my 'slightly better' photo is actually a 1.7 Puma Zetec engine so it doesn't have the extra metal pipe as shown in yours (bottom
left), but in my 1st photo (1.25 Zetec SE) there is a black plastic blanking plug where this pipe goes so I guess you'll need to block this off
too.
The regulator is vacuum operated from the air inlet, so if there is fuel in the vacuum hose then it is possible that your regulator is split/leaking
and the vacuum is sucking the fuel through. It's probably easiest to pop into your local motorfactors and get a replacement if there is any
doubt as fuel in the inlet can only be a bad thing!
I used TigerSeal PU adhesive to block the spare pipes on mine, but make sure you give it enough time to set before starting the engine as the vacuum
produced can easily suck it into the manifold and create the sort of uncontrollable throttle racing that I had when I started my 1.7 for the first
time! (video on YouTube here).
Sounds like you should have it running by lunchtime!

Right, another idiot check!!! The fuel pressure regulator is the 'thing' in my second photo with the square brass bit and the union
clipped hose, right?
If so, Ed, you are spot on as fuel is coming out of the hose attached to it. The only thing confusing me is that the hose is what appears to be Sytec
fuel spec, rather than vacuum hose!
Looks like I'll have to but a new regulator then
Edit to add:
Cue hallelujah music etc!!!!!
The thingy described above is an adaptor that allows the fitting of an external (adjustable) fuel pressure regulator, hence the fuel spec hose and the
mysterious red hose - they attached to the 'new' regulator. OK, so I still need a regulator but at least I understand what is going
on!

Excellent news! A new fuel regulator and a bit of pipe and you should be up and running. I'll keep my fingers crossed....
