ICP denser circuit low
I am once again asking for the great Ford enthusiasts. Replaced injector without a catch. Started the truck afterwards and took 4 cranks (to no surprise). I saw the code right after I started it up. I then proceeded to stop the truck and start it again, and see what the start is like. It’s still very hard to start. Takes about 7 seconds to start. ICP denser low and injector 4 and injector 1 low with a contribution code on cylinder 1. The 1 injector is the one I replaced and had those codes but number 4 is new. I also did the blue spring upgrade while the truck was down. Any ideas as to some ways I can diagnose the ICP and if that is causing my problems? And I also can say it idles at 870 psi oil pressure (was 500 before I tore her apart).

There is a thread on here for how to check a FICM. It has to do with whichever FICM you have, and what pins to check across to know if it's good or not.
It is possible that you overtightened the ICP. There is a torque spec for it when you're threading it in. You also could have gotten something in the sensor if not careful enough. Speaking of, did you replace it with a Motorcraft part or an aftermarket? Aftermarket tends to give bad readings.

Here is what the pigtail looks like on the ICP. Are those red and black wires important? It almost looks like someone tried to splice them all together but only did the blue wire

What year/engine is this truck? I guess I assumed it was a 6.0 because they are more prone to ICP sensor issues. However, that harness is on the opposite side of the engine from where it is on a 6.0, or at least the two 6.0's I had. If this is a 7.3 I'm not as well versed, my 7.3 ran like a tank.
That said, there were (3) wires that needed to be hooked up on my 6.0's ICP sensor for it to function. With only one wire hooked up you're going to get NO voltage, which will throw a 'low voltage' code. I would suggest replacing the pigtail so all wires are the same length.

How much have you driven it after replacing the injector? I can take some time to work all the air out of the system. You might just need to run it more to help clear the codes.

I’ve driven it about 2 or 3 miles (like a baby). Ironically enough I was driving and I heard a BOOOSH come out from the engine. A turbo boot slipped off and damn near scared the **** out of me. I’ll drive it more tomorrow when I replace the pigtail on the ICP. I’ve ruled out a major hpo leak or even a minor one because it still builds oil pressure, with or without the ICP plugged in. But it being unplugged doesn’t change anything so it’s the ICP. The IPR was reading under 30% the entire time as well.

It is 870 at idle and it climbs to about 1800-2000 the more throttle I give, both plugged in and not. If the ICP is unplugged it starts just fine and just throws the 2285 circuit low code for the ICP. But when it’s plugged in it gives me a 2289 code. There are no changes in pressure wether it’s plugged in or not.

Yes.
The good news is you fixed the low voltage issue by reconnecting the wires.
You're now getting a 'high pressure' code. Did you replace the sensor with a Ford sensor or an aftermarket one? These trucks do NOT like aftermarket sensors at all. I had the same code when I tried to run an aftermarket ICP sensor in my '03 with a tune. Strangely enough, removing the tune got rid of the code.
This could be a bad sensor, it could be a sign of bigger issues. You may want to ask around in the 6.0 forum, as those guys are much more versed in this type of stuff.
