This past November I had my #8 injector fail while driving home to my parents place. It started as a check engine light coming on only under acceleration (though the truck was not misfiring at all) but then the following day killed the driver's side bank of the engine while driving. After towing the truck home (with another 7.3L lol) I saw that the truck would start and then after a second, half the engine would turn off and it would idle really bad until I shut it down.
I hit the forums and ended up pulling the valve covers to check the gasket harnesses, but they seemed to look ok and were plugged in. (I stuck quarters under the connectors for the hell of it).
After using a snap-on scanner the following day, the buzz test said #8 injector was bad (high to low side short). I though I read somewhere (also mentioned above) that the IDM could potentially kill a bank of injectors if it sensed a problem with one of them? Don't quote me...
Definitely get a buzz test done. Quick and easy (if you have a buddy with a scanner...)
I wanted to mention though that I was able to eventually fire up and drive on 7 injectors for a while with the truck no longer shutting the bank down. It was definitely missing on a cylinder. Not sure if this was because I cleared codes with my SCT livewire or because I messed with the valve cover gaskets...
Oh, and replacing #8 solved my problem completely. Good luck!
