Engine Diagonistics Question

Hey all, new to the site.

I have a 1996 F-150 w/ 5.0l and 208k!
She is still going strong!!! lol

I have a check engine light on, i bought the truck a couple months back and it was on then too. I tryed to hook up a diagonistics machine, one of those things from auto zone, but no joy, it wont come on or read anything.
The truck runs fine but i have to get the light fixed before i can pass inspection so any help on how to read the codes or how to fix the plug under the dash would be much appreciated.

Thanks

did you borrow the code scanner or buy it? I borrowed one once and used it in the parking lot of the store. It didm't connect so i had to borrow 3 of them till finally one worked.

Any working OBD-II scanner should work fine. Not sure what the problem is at your parts store.

Can you try their scanner on another vehicle? I guess your diagnostic port could have an open circuit in it somewhere.

I wonder if this is a odbI setup. Wasn't Ford late in going to ODB2?

Ford Diesels were late, not gas as far as I know. Was your diagnostics plug located under the hood?

Ford didn't put a computer in a diesel until 1994 when they put the Powerstroke out, and it was OBD-II right from the start, AFAIK.

The gas trucks with a GVWR of 8800 lbs or less were all OBD-I in 1995 and all OBD-II in 1996. Trucks with a GVWR of more than 8800 lbs didn't get OBD-II until 1998 when they stopped making 3/4 ton trucks with the old body style.

Unplug the CEL bulb to pass inspection. Then deal with fixing the problem

A lot of states will fail a vehicle with a non-working CEL.

I suggest buying the 60 dollar OBD-II scanner that just pulls the code and then use google to look the code up for its definition, or even this board. It is worth it as all the passenger vehicles use OBD-II, unless a new version is in the works. That way you dont have to wait for the AZ guy to get time to come out and hook you up. Without the code you will just be guessing at what sensor is throwing the code for the CEL. I thought that an emission inspection could fail you for a non-functioning OBD-II connector as well.
