As said, you can hear it firing but I would say it needs to be spinning over faster.
I know you have said that you have checked the ignition timing but I known proper grown-up mechanics fit plug leads to thr correct firing order, but
with the rotor arm turning the wrong way so you have the timing correct for just one stroke.

Lost count how many times I've checked it to be honest. The arm spins clock wise and myleads are positioned
4 2
3 1
I have tried it rotated 180degrees to be certain I wasn't 180out and got no firing at all then.
So it sounds as though now maybe my battery is too weak? I actually had jump leads on in that video as well!

Your firing order seems to be correct 1,3,4,2 and you have done
all of the checks for timing.
I have just watched both videos and it is turning over slowly but you
can hear the engine catching on 1 cylinder.It could be
that your battery is discharged and there isnt enough power to
turn it over and give a nice fat spark.

SWMBO is at home so just got her to put multimeter on the battery and it's showing 12v

Well that doesnt seem a million miles away.
I have just put a meter on mine and it shows 12.7v
I will still say that the engine is turning over slowly though.

Your battery base voltage should be 12.6 Volts so it might well be not strong enough.

Ok so i'll get the jump leads in it later and see what it's putting out with those on.
What else could cause slow cranking?
Edit: will check and clean earthing point and the bellhousing to starter mounts as well.

The engine hasn't been rebuilt has it? A fresh engine can be very tight
to turn,many years ago we sometimes had to tow freshly built pinto's to get them going.

Not rebuilt, with exception of bolting on the required Sierra bits its as it was as it came out the cortina.

What does it show when you are cranking though? Also measure between starter terminal and engine block whilst cranking and you will see if you are
getting any significant voltage drop through e.g. a bad connection or knackered solenoid.

What about the starter. When i had my crossflow rebuilt the starter was just not up to the job, i checked everything, timing, new battery, jump leads,
plugs, earths, wires, you name it, turned out that the starter just wasn't up to the job anymore. Put a new starter motor on and bobs your uncle
it fired up no problem.

Just checked following voltages
Between battery terminals 12.62v
Between starter +ve and earth 12.51v
Between battery terminals when cranking 9.7v

I would say your battery is knackered! I'm sure someone will confirm.

Am inclined to agree. Hoping it's just battery though and not starter as well.
Have just tried it with jump leads on and got no improvement. Infact battery drained quite quickly.
Quick video to show that once battery/starter issue is sorted we will have life though

If you want any further advice/searching then i strongly recommend this forum.
http://www.turbosport.co.uk/forumdisplay.php?179-X-Flow-Pinto-BDA-and-Twincam
There are some blokes on there that really are pinto specialists. You'll have to register but there's loads of info on peoples pinto and
crossflow woe's. I found it most helpful.
Hope you get it sorted soon
Regards
Leon

Had another look at dizzy timing and did appear slightly out, in the sense the pick up points weren't aligned.
And a quick video, it's definitely closer to starting!

Got it started, kind of. Getting huge backfires though

Move the dizzy until it runs without backfiring.
It is firing while the valves are still open.

IT LIVES!
But... It won't idle, and I have smoke coming out a hole on the manifold I thought was a coolant connection... Anyone tell me what should go
in here?
Oh and of cause, a running video!

Bit of research and pretty sure I'm right and it is a coolant connection and it's just coolant burning off.
Time to rebuild the front end and connect up coolant system!
