best luck i'm currently scanning every page of Volume H Engine/Emissions so I can put it on disc so far I've been at it for 7 hours. I still think its in the clutch wiring somewhere, not that a PCM can't fail, but I got a feeling.

I suggest opening up the computer to look for leaking capacitors if you're gonna remove it.
Hopefully, the replacement you got is for the same Calibration Code as what you already have....

Getting Error Code 67
I did not realize that they processors were unique to each vehicle. I may be in trouble if calibration codes get into play. All I know this is from the same year model and was produced 3 months after my vehicle at the same plant.

Location of assembly doesn't matter, some things you need to pay attention to are:
- For where it was made to be sold (California, 49-state, Canada, etc.)
- Elevation (high-altitude or not)
- GVWR
- Engine type & size
- Fuel & ignition system
- Transmission
- 2WD or 4WD
- etc.
There are ~2 pages of calibration codes listed just for the F-series in 1985:

Replaced Processor Still Get Error Code 67
Well error code 67 is still present even after swapping out the processor. In fact the processor I got I think has some issues of its own. I got a error code 18 popping up after it warmed up. And the truck would eventually die. Put the old processor back in and error 18 went away and it ran and idled smooth. But code 67 still prevails. Jim do you know what the second switch on the clutch does? I understand the purpose of the one that does not function till you press the clutch in. But the second switch eludes me. That switch I have not checked and it may be part of my problem. I also, don't know where that diode is located that it shows in the circuit. Thanks to all who have supported me on this issue.

sorry to reply so late i've been scanning the Ford Manual onto my harddisk so I can put into CD/DVD Format.The fact still remains that in the wiring diagram that wire passes through the ignition switch there may be a fault there as for the clutch switch/s they are either open or closed, I was worried when you opted for the processor, I now have the capability to send you the Volume H on DVD. Do you have a Breakout Box? Your going to need it to fix this problem without replacing things.Let me know if you want me to send you a copy of Volume H and I'll send it to you. If you have a pc you can read it all in its entire capacity.Let me know if that suits you. I'll talk to you later.Sincerely Jim

Code 67
Wow you have spent some time at the computer Jim. Let me know what I owe you for the Section H and I will send you a check. I knew it was a long shot replacing the processor, but it was one of those easy things to try. So that wire passes through the ignition switch. I had a couple of issues with it but I just cleaned all the contacts and that fixed the problem with the starter. Anyway I spent better part of 4 hours checking connections etc. Going to call it a night or morning... Talk to you later.

Error Code 67
No I don't have a breakout box. But I know someone that does! I left word at his home to call me and I will try to get it this weekend. I'm not going to give up on this problem, there has to be a solution. I am going to pull the key switch and see if it is filthy as some of the other items I have dealt with. LOL Thanks in advance for the disc and I will be back in touch when I get the breakout box.

As far as working it, there were numerous changes made in the 1985-86 models due to the evolving EFI system. I know we did all kinds of things to Archion's 86 F-150. Probably any 85-86 EEC will work as far as running. I have a couple of the extras we acquired trying to fix his issue, unfortunately they are all from AOD equipt trucks.

I would go back to Step 1 and verify I'm doing it correctly - correct wires being tested (looks like Pin 30 has a Dark Green/White-stripe wire) and that I'm following the correct instructions for the configuration as it came out of the factory. IIRC there were several possible starting points or sets of instructions (the FA stuff if I'm thinking of the correct thread) in the shop manual, and possibly the installed options were changed by a PO over time, thereby changing how these diagnostics need to be performed....
