SES Light, NO Codes, OD Off light does not work, ONLY when warmed up

[oldracer]

Sorry for the long title but this started last weekend out of the blue. As it says, the SES light came on and engine ran a bit rough and wanted to die but only after getting warmed up? So I plugged in my laptop with my trusty copy of AutoEnginuity with Ford module and whoa, the ODB2 plug was dead! Sooo I replaced fuse #3 under the dash and by then the truck had cooled off so I ran it a while and SES came back on and no codes at all with SES light on, engine idling rough and so on. So today I went to two auto repair shops and both their code readers showed no codes either? I though maybe a trans issue so I tried manual shifting and also pressing the OD Off button and it did not work at all and SES light stayed on.

I found out my advanced Ford module for my AE software was not activated due to a hard drive swap. Soooo Those great folks sent me the activation codes. Here is what I found:

- P0475 on startup but no SES light so I cleared it.
- After warm up SES light came on with P0475 again. Tested the arm and it is free to move?
- Did all the tests and the buzz test returned P1272 for #2 injector both cold and hot? Checked connections external to valve cover and it is good.
- Noted injector control pressure at idle was 520#? Is this okay?

So any ideas and I will have to do the injector after I pull the valve cover it seems to test the internal plug?

I've seen it with a plugged fuel filter, low p-steering fluid and clogged air filter. Not all at same time of course.
