PO275
I performed the FORscan injector electrical test and no fault were found, but the truck running threw PO275, FICM was replaced , Alternator replaced,
if I switch the connector from injector # 5 to the injector next to # 5 what should I get that would let me know if I have a electrical wiring problem to # 5, Or injector # 5 is bad
I also had the following codes throw
PO403
PO405
PO611
P1409
EGR had been removed

What FICM did you buy?
P0275 isn't an electrical code, it is a contribution (running) code. So, you probably aren't going to get any help by switching injector connectors.
Are you having any starting or running problems?
I didn't think that P1409 was a 6.0L code. Was that a typo?

I got the FICM repaired replaced by All Computer Resources
I was thinking if I switch the connector to # 5 injector to the # 7and # 7 to # 5 and if I got a code for # 7 injector being bad then I would isolated the fault to a bad injector, as # 7 is not connected to the # 5 injector.
Is the fault from a 1) bad injector, 2) bad FICM, or 3) bad wiring when the FICM pigtail was rewired
So In switching connector, I was thinking it would try to remove one of the possible faults.

Again - how is switching a wire going to throw a contribution code?
Switch away and see if you can get them all to buzz. THAT certainly won't hurt anything.
You aren't thinking about trying to run the engine with the wires moved around are you?

yes, I was thinking of switching the wire and run the engine. Glad there are people around to keep my brain farts in line
if the FORscan test for buzz passes .. does that not indicate the wiring is good?

You can switch the injectors to see if the contribution code follows the one that was in the #5 hole.

so for switching the # 5 injector with the number # 7 injector .. just for testing I think I do not have to worry about the replacing the Nipple cup/ball tube o-ring seal ... just to determine if the FICM is bad or the # 5 injector ...
is their another way to test if my # 5 injector is bad or the FICM is bad.

Send your FICM in to be tested if you don't want to be messing with oil rails and injectors just yet, but you posted that you already repaired and replaced the FICM. That said if you are still getting a P0611 code, then the FICM may STILL have an issue. Call All Computer Resources (the folks that rebuilt your FICM) and see if they test the FICM. If not, that is why I like FICMRepair.com.
How old are the injectors (how many miles), and if they are not the original, then where were they purchased?

and I thought I was dealing with a good company. When I called this morning,, got their input on the error code,, whereas they felt it as the # 5 injector and not the ECM.
Now I got to decide ether to buy a new injector for # 5, or swap with # 7 and then see what happen.
Describe the error code as not a electronic issue but that # 5 was not pulling it weight in the performance of the motor

Uhmm, that is what the "contribution" part of contribution code means.
You are mistaken if you think it can only happen from an electrical perspective. Both an injector AND a FICM can cause a contribution code without it being an electrical issue. And if I had done the FICM job (ie All Computer Resource), I could see the temptation to just blame the injector (which it of course could be).
Anyway, I wish you luck with it.
