injector diag needed

I have a 2003 6.0L. I need help fixing my truck here. when you first start the truck in the morning the truck runs good ,but when it gets warm up it starts the misfire in number 5 injector. When I pull the ficm harness from the injector plug at head it as change in engine preforness. I checked power to the injetor 5 wiring plug and had 12v 28v 11v 28v solid power no pulsing.I checked the coils of the injector and was good.I also checked the power at other injectors and had fast pulses of power but could not read it. I even tryed a ficm out of a f-550 2005 but I have 2003 f-350. I changed injector 5 and engine oil also and still same problem is there. the only codes i get is a cylinder number 5 code. any idea's?

Sounds like a problem with the IDM.

I just thought about this, but the pulsed power is so rapid that your multimeter may view it as constant.

I agree. It sounds like a FICM failure.
