Did you try just reseating the prom? That classic ECM used a crappy socket and prom holder. I have one of those ECMs here but its a different service number.

Thanks for the reply Brian,
I haven't seen the truck in person yet and I will try all the normal steps when I get there. Do you remember what prom that uses? 2716, 2732???

That looks like same PROM cage as 7747? The one I have is even older version I guess.
