2004 Camry Turns Over But Won't Start

OK, I'm officially stumped  - I have a 2004 Toyota Camry (3.0 L) that turns over
fine, but won't start.  My nephew was driving it and he said it just died.  Here is
what I have done so far:

- Read the codes.  There were three codes and all three were ABS related.
- Replaced timing belt, and tensioner - The original was not broken, but it had
200k+ on it.  All marks were lined up perfectly after installation.  (Although I
admit that I wasn't able to find anywhere in writing where the rear cam timing
mark is on the timing cover plate.  I "assumed" it was the indentation in the
middle of the top mounting tab, so that's where I aligned it to
- Checked for spark - Good.  Initially checked with a probe at the coil pack, then
grounded the plug.  Both ways worked perfect.
- Checked fuel.  I'm getting 40 psi when cranking, then goes down to 10 psi.  I
also tried spraying starting fluid into the TB.  I also verified that I am getting 12v
to the injectors.
- Checked EVERY fuse.
- Checked both the crank and cam sensors.  Each get good voltage (approx 3-5
mV) when going across an iron object.

So I've got fuel, air and spark, but no bang.  The only thing I can think is that
there must still be something wrong with the timing.  I would think, however,
that I would at least get a little burp or something; but I get NOTHING!

This is driving me crazy!
