I think you're right on this one. First, IIRC, the PSD uses an OBDII connector for the OBDI computer. Second, the 94 and some of the 95 PSDs are hard to get anything to do much with their computers. The shop I worked at had a NGS Star scan tool (that was supposed to be what Ford used). It would do WAY more with a 96/97 PSD computer. Some of the 1995s worked that way too. It was probably the build date that made the difference.Directions that come with it says it doesn’t work on my 94 7.3 idi but I think they are talking about 94 7.3 di.
I have a reader from Amazon and it works fine the few times I have used it. Directions that come with it says it doesn’t work on my 94 7.3 idi but I think they are talking about 94 7.3 di.

I have a 94 na and have this exact reader. Works perfect. I highly recommend getting the extension cable. No it's not necessary but makes life nicer.
I struggled without the extension cord for over a year until I realized how much easier it was to sit in the cab of the truck and work through issues. The extension cord is as valuable as the reader.Ok, I've ordered the 3145 OBD1 reader from amazon. I'll probably get the extension cord and the book as well. Anything else I should know about?
From my experience with mine and others in the past, just follow the instructions on the screen. Just to pull codes, you shouldn't have to press the accelerator.Going to need to use this again today.
I have a question, first.
The instructions say, plug in reader. Turn on key. Do not start engine. Read codes.
That's it.
But I have read a couple places on here, something about not getting accurate codes, if you don't depress the go pedal.
Is that true?
If so, do you depress the pedal before you turn the key on, or after? Do you just hold the pedal down, or release it?
