Yup, my plenum gasket was toast (pics)

Well, the rebuild did not go as planned. I should have listened to you guys and bought new injector O rings. Two of them broke when I put the fuel rails back on so all truck does is spew fuel everywhere. I should be able to fix that in a second tomorrow and then we'll see if I actually fixed the plenum or made it worse.

Make sure you lube them with light oil (PBlaster works great) when installing them.

I couldn't figure out how to disconnect the fuel line. I bought a 3/8" disconnect tool but I still couldn't get the dang thing off. I know now that it would have been a LOT easier to just take it out as one unit, but, it's too late now.

Took me 2 trips to the part store and 6 attemps to get all 4 injectors on the drivers side to seal right. It seemed like everytime I fixed one seal I would just destroy another. The truck runs GREAT now and and there's absolutely no pinging. Plus my truck heats up twice as fast with the new thermostat. I put some Seafoam in the oil and in the gas to clean everything up nice. I'm gonna do an oil change thursday and after that I should be all set.
One question though, are the little metal clips that hold the injectors to the fuel rails essential? Or can I run without them for a while? Two of them went shooting across the engine bay while I was trying to install them and I never found them. Nothing seems to be leaking now but I just want to make sure.

It would probably be a good idea to replace them. You don't want fuel to start shooting out at the wrong time and start a fire!
When I did mine I had problems getting the fuel line off as well. I ended up cutting the flexible line between the rails and just flopping the left rail over. I wanted to pull the injectors so I could clean them and the intake was so nasty and dirty that I wanted everything off of it so I could clean it. I replaced that line with some standard issue high pressure fuel line and a couple of hose clamps.
