TFI Module?
1985 Escort blew out 2 Electronic tfi modules in its long history ,and stopped me dead up till the tow truck arrived got fixed at the dealer.
My 1985 300 6 has this original module attached to the base of the ditributor. If I get a spare and need to fix it on the side of the road . How does the old one come off ? Has anyone ever done this job? What size are the tiny nuts which hold it on.
Thanx , Malcolm.

You simply unplug the wiring and take the two bolts out. But there is a catch, you do need a special socket to take it off. You can take a regular 1/4 drive socket and grind on it to reduce the diameter for it to fit, or you can go buy a special socket for it in the store. They haven't used the TFI in years, so you might have to go to Amazon or somewhere online and buy the special socket if the store doesn't have it anymore.
P.S. The new module will come with a packet of grease. You have to use a lot of this grease or the module will tend to burn out. It goes between the module and the distributor.

Are you sure of the year of your 300 cubic inch 6 cylinder? Does it have a carburetor or is it fuel injected?
Anyway I think I can answer your question. There is a special tool to remove the ignition module from the side of the distributor. Many auto parts places probably still stock it or can order it. I believe the size of the small bolts is 7/32 but most sockets of 1/4 inch drive don't have a skinny enough nose so you need the special tool.
You just remove the 2 small bolts and pull down on the module to remove it.

If you had a 351w and it was not a HO but had 2 barrel carb, also had the computer system with the TFI carb.

7/32 Roger That., Thanx for the quick replies.,and thanx Franklin.
My 6 is carbeurated. There is a spiel in the Ford Shop Manual about the module. I may be wrong ,but f I remember correctly there were 2 different modules and duraspark was also mentioned but I think I eliminated mine as a duraspark . Mine has the module on the distributor ,I know it can stop your engine and I think it is called a TFI module.I was a little hesitant about buying an extra online because the part numbers were close but not exact and not wanting to somehow order the wrong one.
It's hard to find the correct socket size because none of my 1/4 inch drive sockets fit in there.

If you have a bunch of wires going to the dist. into a box type thing it is TFI system.
DSII only has 3 wires to the dist. and the IGN box is bolted to the inner fender.
As for the 7/32 socket did you read the part you need to grind it down to fit?
The end that fits the bolt is to thick so it needs to be made thinner to fit "INTO" the hole the bolts are in.
Your socket is not fitting INTO the hole and why it will not fit.
Thing is it cant be too thin or the socket could crack when trying to undo the bolts.
On that Escort there were fun to change NOT!
IIRC they were on the back side of the motor and under something? Manifold maybe?
My dad was given one because the TFI failed and I was the lucky one to change it out.

I read about grinding the outside of the socket down to fit over the nut. Just by a lucky chance my tool box has a baby 7/32 nut driver made for small nuts and small work . I hope the handle is hefty enough to turn the work by hand but it has a straight hex handle that will take a small spanner for leverage if required. . I guess I'll head over to Amazon and put in the part # written on the existing module and try for a match up.Some of them aren't all that expensive, but the originals from Ford were over $100. at the time and almost $200 nowadays.
Many Thanx
