why is it the injectors

Ok, I have no power when the truck is cold.
3 injectors fail the buzz test only when cold.
The truck runs fine with no missing and no smoke.
Why is this the injectors. I do not understand. The truck is out of warranty, and I do not want to swap these out if it will not fix the issue.
Please help me understand.
thanks

They have said they do not pass the buzz test. I do not know much about this thing.
The truck runs good and has no smoke. But until it has warmed up about 10 min. it has no power. it came on slowly, and just keeps getting worse.
If the injector was bad it would miss, correct? I do not know what it would do if it were weak.

did your truck miss when cold, or just have no power?

doesnt make since that they failed the buzz test , if the wiring is bad it will be bad hot or cold ,and 6.0 arent bad for injector wiring problems , now back to your issue , it very well could have failed cylinder contribution test cold and passed after warm , normal for 6.0 with worn injectors to do this , do not replace any injectors until you are sure that the truck has been reprogrammed with the latest calibration from ford , if not do so, may fix your problem, has fixed many withgout any parts replaced , as far as why they fail, they are worn internally ansd sticking cold , not allowing them to operate properly , after engine is warm the metal expands allowing all internal injector parts to function properly, thats why they fail cold , still dont see them failing buzz test cold unless ficm is getting ready to fail, which is possible but not likely

Ford did the latest and greatest software. and it did not help.
After he said that I can hear the buzz I guess it is when you turn the key is not smooth as it was.
Is this due to anything I did? or just failure. There are no codes. anything short of replacing them?
