Injector no worky
Brand new UVCH, but I still have the original gasket frame. It passes the buzz test, but not the oil test as seen below. Injector has been giving me fits since I installed it and I never had this problem until I put the injector in. Who else has run into this? I can Buck$Zooka more parts in there, but I'd like to exhaust my other options first. Armature clearance (which I have to read up on and buy feeler gauges)? If nothing works, I'd have to air freight another injector from FFD to get it installed before my trip.

Its possible the armature plate screw loosened up. If so, then its an easy fix. Remove the solenoid and if the plate spins around then its loose. You simply tighten up the screw. However, you may have to index the poppet. I can walk you through that process over the phone. Let me know if you would like my cell number.
The injector does not need to be removed for this process.

Nothing beats modifying a daily driver, huh?
Well, I guess a reliable vehicle might.
Nothing against ANY vendor/manufacturer of aftermarket parts because stuff can happen to anybody at any time, but nothing beats the reliability of stock parts. This is why I don't modify the stuff I have to depend on day in and day out.

Replacing the injectors and turbo is giving me a lot of education... now I could use a lot of medication.

Bummer.
When the engine is running, can you feel the solenoid clicking? If not, then you might try swapping it with another injector to see if the problem follows the solenoid. Usually a bad solenoid will shut down the whole bank but not always...

The odds of another bad injector are pretty darn slim. Can ya stick a test light or volt meter on the connection to see if it is getting the signal to fire?

I am in the market for a set of injectors in the near future for the F450 (hopefully it lasts till after i get the tax return..) I was thinking of a set of remans, and had looked at Full Force. I am waiting to hear what is up with yours.

I hope this doesn't reflect badly on FFD... yet. You really need to factor my luck into the equation. New injectors and turbo prompted replacement of IPR, boots, and plenum? All at the same time? This last year has really thrown the produce at me on the stage of luck... not just with the truck.

More tests:
Behold! The procedure for "listening" to a single solenoid with a camera.
Engine running - you can see #3 injector putting out a good flow of oil on every trigger.
This is injector #1 with an underwhelming dribble.
Camera placed on running #1 injector with microphone blocked. You can hear the solenoid fire.
I checked the temperature on the exhaust manifolds at all cylinders.

I checked the temperature on the exhaust manifolds at all cylinders.
- Cylinder 1 is 30 degrees colder than cylinder 2
- Cylinder 3 is equal to cylinder 2.
- The passenger side total temperature does not get as warm as the driver side total temperature.

How many miles on the new injector? Sometimes they need break in as all parts do in the rotation. It wasn't even oiling before you said, so take a long drive, at speed, push the throdle down a little or a lot, pull back apart if you need to. Its sucks I know, but if there isn't many miles on it this mit help. The heat gun is telling you something for sure, but because you have a trip coming up its worth a try.

About 400 miles. It's been coming amd going since day one, but it rarely cleans up. I'd hate to be far from home while burning 7 cylinders. They are remans... the very first time I skimped on the truck.

Hey rich I feel your pain. After I got my 2nd set back and installed I had not driven it much but everything seemed good until the other day. I developed a problem at idle. Won't go into details on your thread but I have 7 cylinders below 1(perdels) and 1 above 5. I know some say the numbers don't matter but I don't buy it. I'm not going to mess with it for a while. I will let you get yours all figured out then I will use your knowledge that you gained.

Interesting videos....Almost looks like a weak solenoid, yet the buzz test sounds strong. 
FYI, it is reasonable to swap injectors and reuse the o-rings and copper washer while you troubleshoot your issue. You don't have very many miles on them right now so they should hold up well enough. After you get this figured out, then you can go back and replace o-rings and washer on the disturbed units.
