I just finished checking all of the fuses, and they are all good. I pulled both the EFI and ECU fuses to reset the computer, keep them out for about 30 seconds, and still nothing. The ECU is making a very audible click, almost like the sound of a blinker going a single time, "click-clack", when I turn the key on. I don't know whether it has always done this and I am just noticing it now, or if it is new.  

The search for the cause starts in ernest tomorrow, I really suspect my computer has died though. I forgot to mention in my first post that, when I was driving it today, I did notice that the RPMs were somewhat erratic, not racing, but sure didn't seem normal.
