Seeking help with (probable) fuel injection problem 200 1980

I did a compressino test, this was mentinoed in the original post. But since that post was so long, I can understand not noticing it.

It has 175 PSI in two cylinders and 150 PSI in other two. 150 isn't great, but is enough to run.

It does happen to be one of the 150 PSI cyls that doesn't run, but the other 150 PSI cyl is running.

Given the three necessary things, I have adequate compression, I see a spark, and so I suspect fuel. I have swapped plug wires and injector with a running cyl, and that running cyl stayed running, the non-running stayed non-running.

So a new question: Is it possible for the fuel system to fail on only one cylinder like this? Or does it tend to be all or nothing?
