Hey, I'm in the process of picking up all of the ignition parts you described. My question is, the TFI coil part number you list, (AC Delco F503Z) my local parts store can't seem to cross. They show a listing for ALL 83 F150 V8's to use a AC/D F502Z or equivalent. Is this the right part? What is the difference?
Thanks in advance.

I'm running into same problem, they only have a listing for the canister coil...

Also, I have all the other parts, minus coil and plug wires.. Is there supposed to be an index to ensure proper orientation between the cap base and distributor housing? Its held on by clips, and I've succesfully mounted it both ways. I could try and get pictures if nessecary... Thanks.

/wwwthreads_images/icons/cool.gif Dear Rock. It's cool/wwwthreads_images/icons/cool.gif that you are making this upgrade, and I'm sure that your Jeep will pay you back every time you crank it up. As for the coil, the 1983 Ford 150 pickup with the non-EEC engine should be the right one./wwwthreads_images/icons/wink.gif TeamRush is in Daytona,/wwwthreads_images/icons/smile.gif and he will be flying back tomorrow AM. I heard from him a few hours ago, and he has had a great time; watching the races;/wwwthreads_images/icons/smile.gif seeing friends from the racing business;/wwwthreads_images/icons/smile.gif getting sunburnt,/wwwthreads_images/icons/shocked.gif diving,/wwwthreads_images/icons/crazy.gif and yes.....chickwatching./wwwthreads_images/icons/wink.gif I'm sure that he will check the BBS sometime on Tuesday and will see your post./wwwthreads_images/icons/tongue.gif

CJDave, That was the year make model truck I gave the guy, and he looked at 86 and 81 also, all three years, including f-150 and f-350 with V-8's all refrenced a canister coil... I didn't have the part numbers for him to cross refrence, but I'm going to go to another parts store with the part numbers to see if they can do better...

And as for those daytona terrorists.. err , tourists, race fans, etc... I love the race, I could just do without the fans... hopefully we'll get our town back tomorrow... Sorry - just been cooped up for past four days because I've been trapped by traffic...

I just converted mine to the tfi coil. I think I had to go to an 87 ford f150. My parts manager friend told me that all the tfi coils were the same. By the way it works great. I even turned my idle down to 550rpm which I couldn"t do before - especially with the fairly heavy cam I have.

I had the same problem at Autojerks so I went elsewhere. You will have to ask the parts guy to get out the AC Delco parts book and low and behold there it is. Yes TeamRush is correct on the Part number. I bought a Borg Warner Select and on the top of the box it Says E92 Ignition Coil. I hope this helps.

I do have one question: How did everyone who has already done this mount the COIL? I am in the process of doing the up grade and need help quick!

I mounted mine on a short piece of 1X1 angle iron and then to inside fender. The wires I got were for a 87 f150 w302. and it included
a long primary cable.

Get the coil for a 84 F-150. It has the TFI coil instead of the canister coil. As for the connections to the coil put some female spade connections on the green and red wires. The red one goes to the and the green one hooks to the -.

I wish that I could tell you how it all works but the one I did it one must have a bad vacumn leak somewhere and I am in the process of figuring it out.

As far as I could find there is no TFI coils.
84 F-150 , 88 tempo , 94 escort all the same!!!!!!!!!!
Mine works great.
I only have one question.........
Why do I have a "damp morning" (moister problem)?
I lose 2 to 3 hundred rpm on a damp morning. I've had this problem on some other Fords. Just wondering!!!!!!!! Help Team Rush!!!!!!!!!!!
Work great other than thet/wwwthreads_images/icons/smile.gif/wwwthreads_images/icons/smile.gif/wwwthreads_images/icons/smile.gif

OK this looks like a better post to ask this,is the square laminated type coil with a rectangle shaped connector on top that accepts
2 female spade connectors from a 85 Tempo with TBFI the same coil everyone is looking for? It also has the male end for the coil wire
I also looked at my sons F-150 ,a 89 model with FI and a 302 and it has the same coil that the 85 Temps has..

I did some research at different parts stores as I am in the process of doing this upgrade and these are the part #'s that came up for the coil:

TFI Coil Information:

Standard Ignition P/N: FD479
Niehoff P/N: FF-179
AC Delco P/N: F503
Borg Warner P/N: E92

CJ Dave Says you all didn't miss me one bit!
Says some of the silly ones here even slept better while I was gone on vacation...
I'm back, AND READY TO RUMBLE!!!
LET'S GET IT ON!!

-------------------------------
*RocknCJ* asked,
*My question is, the TFI coil part number you list, (AC Delco F503Z) my local parts store can't seem to cross. They show a listing for ALL 83 F150 V8's to use a AC/D F502Z or equivalent. Is this the right part? What is the difference?*

The difference is there is a misprint in one of the factory catalogs, and you have been going to the stores that handle that companies' products. It's pretty common for cross over information to be wrong in the chain auto-jerks stores catalogs. They have a brand they push, and they don't worry about being accurate with the other stuff.
The P/N is correct. If you look at the bottom of this thread, you will find a post from 'Kahuna' that lists 4 or 5 part numbers, try one of them.
-------------------------------
*FlMudCJ* asked,
*Is there supposed to be an index to ensure proper orientation between the cap base and distributor housing? Its held on by clips, and I've succesfully mounted it both ways.*

There should be a little metal tab screwed to the housing, or a tab sticking up cast right on to the housing to locate the cap or cap base, depending what model of distributor you have. If the tab is there, and you can still mount your base both ways, GET A BETTER QUALITY BASE! If the tab is missing, there is a screw hole right in the middle of the word 'Motorcraft' cast into the side of the housing, the tab goes there. Beg, borrow, steal, or fabricate one....

*And as for those daytona terrorists.. err , tourists, race fans, etc... I love the race, I could just do without the fans... hopefully we'll get our town back tomorrow... Sorry - just been cooped up for past four days because I've been trapped by traffic..*

WATCH YOUR MOUTH-- I RESEMBLE THAT REMARK!
Yes, I was just one of those ballistic rental car drivers! You may have the town back until the first of March... When with any luck I'll be back... On a bike this time....
--------------------------------

*Dirt Dog*
*As far as I could find there is no TFI coils. 84 F-150 , 88 tempo , 94 escort all the same!!!!!!!!!!*

Did you mean 'No TFI Coils' or 'No Difference In TFI Coils'?
There was a factory defect in the Motorcraft coils until they were re-engineered in '96, so I don't recommend a pre '96 coil out of a junk yard. All of the replacement aftermarket have the defect fixed, so any one you buy should do the trick.

*Mine works great. I only have one question... Why do I have a "damp morning" (moister problem)? I lose 2 to 3 hundred rpm on a damp morning. I've had this problem on some other Fords. Just wondering!!!!!!!! Help Team Rush!*

The only things I can think of are,
1. Some of the vacuum switching and choke pull offs will be affected by added moisture.
2. Ford has a fully vented distributor cap and distributor housing. The moist, damp, dense air may be affecting the voltage transfer inside the cap.
3. Moist air may be making it possible for large amounts of spark energy to escape the distributor cap and plug wires.
4. Cold, dense, moisture laden air may be leaning out the carb mixtures. The carb just 'sees' volume, and can not compensate for density.
5. The added moisture and density may be affecting the spark travel in the cylinder.

(And I bet you thought there would be a simple answer!)
--------------------------------

*LoneEagle* asked,
*OK this looks like a better post to ask this, is the square laminated type coil with a rectangle shaped connector on top that accepts 2 female spade connectors from a 85 Tempo with TBFI the same coil everyone is looking for?*

Correct. See Kahuna's post for replacement part numbers from most major manufacturers.

*It also has the male end for the coil wire I also looked at my sons F-150 ,a 89 model with FI and a 302 and it has the same coil that the 85 Temps has.*

So take his coil, mounting bracket, and coil wire and tell him mean elves stole it!
Talk about having a donor vehicle in the yard!

*Kahuna* stated,
*I did some research at different parts stores as I am in the process of doing this upgrade and these are the part #'s that came up for the coil: TFI Coil Information:

Now here is somebody doing their home work! TWO slices of raisin pie for you my friend!
You are correct on three of the four part numbers I can identify, so I assume the fourth is correct also.
You found a parts store with a REAL interchange book!

*My other vehicle is an Aircraft Carrier.*

Kind of hard to work on it in the driveway, isn't it?
----------------------------------

NOTICE!
I MISPRINTED IN AN EARLIER POST,
THE COIL YOU ARE LOOKING FOR IS OFF OF A 83 AND NEWER TRUCK-- WITH ECC.
In an earlier upgrade article I wrote 'With Out EEC', and that is incorrect.
-----------------------------------

Later folks, hope this helped clear up the confusion! Aaron.

When I go off-road my engine spends about 1/3 of the time under water or mud, how do I make the Ford cap fully sealed?

Yea that's just what I needed! Looks like you got your answer FlMUDCJ on the orientation of the cap. I got the 8mm wires from FOMOCO (Motorcraft). Very nice! Excellent Job Kahuana, the part numbers will be a great help to all. /wwwthreads_images/icons/laugh.gif

Rush thanks for the reply.
I meant to say I couldn't find any non eec tfi coils. Sorry I've gotta start proofreading my stuff. I can think better than I type./wwwthreads_images/icons/smile.gif
My questin on dampness was about I never had this problem w/ the factory ign. or the hei. It just started after I did this switch.(which by the way works kick a$$. just as good as the hei and easier other than this problem)
My rundown on parts are..
Used(new)lower cap
new cap/rotor
wires stayed from the hei(accel 8mm not too old)used a piece left over for coil wire w/ new boots and ends
same plugs (about 3K) 045
coil off 98 mustang 3.8 (2200 miles)
Let me know if something doesn't sound right.
I have another question. I put the condensor back in place where it was.(on pos. side of coil) Is this right or wrong , or do you even use it?
Thanks.

I knew everything when I was 16......How come I'm so stupid now?

That all looks correct. I can't tell how you have it all hooked up, so I can't be sure...
The 'Condenser' on the coil wiring harness is a hold over, and shouldn't be needed.
Some times that capacitor will help keep noise out of the radio, and it shouldn't hurt anything.

If you idle problem only happens with this ignition, it make me wonder if the vacuum advance and centrifugal advance is working correctly?
Are you sure your module isn't sliding out the back door on you?
I just can't think of anything else that would affect the idle speed when you first start it, and then go away when it warmed up...
The only way the Ignition can affect Idle speed is by advancing or retarding, or if the module is going south...
Maybe it's something I over looked, or have never seen happen before...
I learn something every day...

Ford caps have a really nice vent in the top of them, and that really is a good thing.
That vent will let moist air in when you shut the vehicle off, and the moisture will condense in the cap over night. The quick way to tell if this is the problem or not is to pop the cap in the morning, and look for moisture.
I usually use one of those dry air cans for computer stuff, and dry it off anyway. If it starts right up and runs fine, you just found the problem.
If it continues to loose RPM, look elsewhere.

I used starting fluid to dry the cap and distributor after drowning out.
It cleans everything, drys residue free, it dries in a few seconds, and it's cheap.

I had a kid working for me that didn't know to blow the fumes out of the cap before putting it back on... Got in, Hit the Key, ..... BOOM!
You guessed it, 12 miles from nowhere, and he blew the cap apart!
(Lucky I was much thinner and in much better shape back then...)

Now I use the canned air, it's a lot safer in the hands of a kid or non-thinker... and it's supposed to be more ozone friendly, but it costs a lot more and takes a lot more of it.


Is the choke engaging and pulling off correctly? About 70% of 'stupid idle' and 'instant' drivability problems that show up in the late fall turn out to be choke hardware that wasn't a problem until it got colder...
