Firstly, I'd double check the porcelain on plug #3 to make sure it isn't cracked, and also I'd test that plug wire with a DMM to ensure the wire is actually good and reading @ 3000 Ohm or less. (I've had many sets of brand-new plug wires that came with a faulty wire, It actually happens.)
Once that's done and if the wire is certainly good, Pull plug #3 but leave it hooked to the wire & crank it to check if there's actually a spark, and if so what color is the spark producing?
As far as fuel injectors go, You can view the PWN circuit signal for your fuel injectors to ensure they're all operating the same, But that would take a rather decent O-Scope if you may know where you could get your hands on one. (Not sure exactly where the pulse widths should be at, but each injector's PWM should certainly perform consecutively with each other). But note I've seen numerous of these with injector leaks, but not one single instance of one instantly failing that caused it to completely miss.
Unfortunately man, I'm kind of expecting this to be more of your problem then anything.
With that issue, I'm willing to bet you it's leaking way worse then you think, As the engine gets warmer & heat soaks, Everything literally expands and your leak gets bigger. And vise versa; Being colder means the more contracted everything your leaks smaller.
If you're not seeing it leak after you've driven it & warmed it up, Then that leaky intake has heat soaked & expanded enough to begin sucking it into the runner(s) and into the cylinder, rather then just seeping out the sides like you've seen.

She does leak antifreeze. I know the lower manifold has been leaking off and on. Normally if the truck is only ran for short amount of time she weeps out the front. If I run it for a longer period of time she seems to be okay.

Just pray to god that's just an exhaust manifold leak & not your valvetrain doing a war cry from attempting to combust antifreeze, heh..New development is that I can hear a mechanical clicking noise on that side of the motor.
