I am thinking grease congealed in the mechanism, preventing the contacts
from hitting for a few seconds, eh?

Cheers,

It doesn't wait for anything. If you've verified the grounds, battery
feed and and power from the ignition switch, the PCM is toast.

Yup, I verified all these things and they are just about perfect. I
was pretty sure and hoping one of these would be bad. I took it to
the dealership today for diagnostic check just to make sure but at
this point I'll most likely have to buy a computer.

If I get a used computer, what do I need to look out for to make sure
it is the right one?

Make sure the part # on the new one matches the part # on the old one.
