CRA 1226865 86 carb file

[In-Tech]

Hiya folks,
I was called yesterday to help with a stock application that is throwing code 51 fail. I think it's an '86 Truck 350 electronic carby. I looked here and don't see one of those files. It's older than dirt and is actually a prom and not an eprom. Computer controlled quadrajet stuff. Do any of you have a copy of this CRA file or options thereof? What is this prom? Can I replace with a 2732a? File size? Stackable? lol any info is really appreciated

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???

Here are some pics that were texted over.

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