Bluffing may well be slightly better when running good. Certainly the more fishy players may very well say "he always has it" and make a hero fold.
In addition, though, this is one of those things where the human element of live poker is really pretty important to understand. In other words, bluffing is a mathematical problem. To put it bluntly, you bluff when you have enough fold equity against the villain or villains' range to justify the odds you are getting on the bluff based on the pot size. So if there are 10 bets in the pot, you bluff if you have a better than 10 percent chance of inducing a fold.
That math doesn't change when you are card dead. (Indeed, as you note, it can get a little worse because when you are running bad people may call you a little more giving you less fold equity.) What changes is that the desire to win a pot and/or boredom may make a player more willing to bluff without correct pot odds.
(Note: it is POSSIBLE to end up in situations where being card dead can increase your fold equity a bit. If you haven't played a pot in 3 hours and then open with T9s on the button, you may get something that ought to call you to fold, especially if the BB has no experience playing against you. But by the same token, if your opponent does have something or make something, he or she may play it way ahead/way behind if he or she puts you a tight range, which can make multi-street bluffs expensive.)
So that's why we have to be honest with ourselves and make sure that when we are card dead, we don't increase our bluffing frequency into situations where we don't have enough fold equity against the villain's range to justify it. It seems weak to just keep folding rather than trying to take down a pot, but you can't suck blood from a stone either.
