THANKS! I've been working on something like a Drone, and during the prototyping fase, the tires ran into the sd card and the card stopped making contact. I've been searching for hours(possibly over a day) for the solution! And simply by pressing my thumb on the card..... IT BOOTED! Bitter sweet to have such a simple solution to a problem that perplexed me for so long.

If you have an image that is not 100% correct for some reason, you could be successfully flashing it to the SD card, but it would still fail to boot the RPi.
Also, does the green ok led flicker at all when you power up the pi?
Some times the contacts for the SD card do not actually make contact so gently pressing the contact area of the sd card down as you power it on might get it to boot. You would then need to carefully bend up the spring contacts for the sd card. The wiki I believe describes how to do that.
Just a couple of possibilities.
