The Ford diagrams do not show the internals of the computers. They only show the pin assignments for the input and output to the box.

Good luck,

yo,

Fred gave you da correct skinny on the EECs.

Typically the EEC connector terminals are corroded or wiring is damaged

or, the large capacitors leak or burn.

Capacitor Repair in a 90 5.8 Source: by seedpress (dolittle) at Ford Bronco Zone Forums

See pic, etc. Good Job!

another burnt CAP pic by Ken @ http://img.photobucket.com/albums/v312/kermit0069/ECM002.jpg

---------

"...The patient in question is a remanufactured A9L unit. This ECM is the one from a little notch project I'm working on. It started giving some problems starting up, engine flooding, random hesitation, missing and stalls. I opened up the ECM (the car is running with a A9S unit) after the owner brought it for a checkup.

What you see is the typical electrolytic capacitors leak, causing intermittent shorts/opens to the neighboring circuits/components and symptoms as the ones explained. Worst case scenarios with this type of failure, is a permanent no start and permanent damage to the PWB preventing it could be repaired. As soon as I replace the capacitors I'll update with the pictures showing the repairs. The following capacitor does not show any leakage problems however, it will also be replaced as a preventative measure..." read more by Joel5.0 @ http://sbftech.com/index.php/topic,15654.0.html
