I took a wild guess and figure he calls the FPR the "pressure control valve" in his first post, if you are referring to the Fuel Pressure Regulator. The SAE definition of the FPR abbreviation is Fuel Pump Relay, so there is some ambiguity in our Brickboard slang.
If the 92 has no cold start valve, the 561 ECU is not its original. But that's not the problem, because, if anything, that would make it would be too lean in the cold.
But you're right, this has all the smell of a fuel pressure regulator despite the attempt to rule it out, like, first thing he did. I think.
