This is a likely solution to your Mac Pro's failure to power up. The symptoms I experienced began with having to press the power button twice to get it to start. Then it took three or four times and finally it wouldn't boot at all. If you haven't installed one before (like I hadn't), you can find tutorials on Youtube, but be sure they are talking about the same model and year that you have. Of course, you can have an Apple Store do the job, but you will pay waaaay more. My net cost was $100, buying used and installing it myself.
