Subject: Initial Engine (not) starting with EC2 - suggestions appreciated!

I have just this weekend gotten my rebuilt electrical system to the point of
being able to try and start the engine. I thought I would post what is going
on so far, and ask for any advice and suggestions about continued debugging.
I'm a noob at this so suggestions are appreciated. Thanks in advance!

I have the EC2 + EM 2 system, on a GEO 1.3 liter 4 cylinder engine. The
electrical system is a 'Z-19', (a la Aeroelectric Connection).  The brand
new engine was last started in July 2007 and run for about 1 hour with the
EC2/EM2 to a maximum RPM of about 3200, but with different coils. The
igniter/coil combination burned out, thus leading to the electrical system
redesign. The entire electrical system has been replaced with the Z19.

Here is what I have so far:

5/2/2009- EC2 Diagnostic checks:
EC2 relay check for A & B controller - OK
Injector test - OK
Coil test - OK
EC2 Knob checks (Hex readout) - OK

5/3/2009
Crank Sensor test - OK
Fuel pressure - FP 1 brings pressure to 43 psi. FP 1 + 2 raises pressure to
46 psi. Sound of FP 1 is a steady whine. Sound of FP 2 is kind of up and
down, but pressure remains at 43 without variation.  The two fuel pumps are
purchased from Tracy/RWS.

When attempting to start a small amount of blue smoke is seen from the
muffler. Not much. A few times it sounded like it almost started, but did
not. That is the exception. For the majority of attempts to start, the
starter motor turns the prop over and the engine coughs but does not start.

Thanks!
