No problem there Bill. I was scratching my head on this one and recall a recent thread about diesels and code retrieval on mid 90's trucks. I was not aware if that also applied to a 1990 model. I learn something new everyday too

That's true, no diesel ever had EEC-IV. The two digit codes are almost the same. The transmission controller with the diesel has a few unique codes that are not in the gas systems.

The 1994-1997 Powerstroke diesels had EEC-V controllers, but unique software. The software was strange, and was written outside the mainstream Ford software development community. It was somewhere between OBD-I and OBD-II.

[QUOTE=subford;15367647]I did not know it was possible to get codes on a 1990.
How would you do it?
Did they even have codes back then?
This question has come up before and I do not think anyone was able to get codes out of one.
I do not think they ever had the OBD-1 system on these trucks. They used some off the wall system.

What engine does the 1993 have in it?[/QUOTE

The 93 Has A 351efi. 5.8
