Volts ARE volts, but the work gets done by the Amperes.
Check to make certain that the wire size to each coil is
large enough to carry the maximum current the coils can
draw. Check for high-resistance joints (e.g. cold solder, too small crimp surface, too little crimping force) in
each coil's supply.

Thanks
for all the input.
After
a few calls to Tracy and a little help from Buly I tracked down the problem(s)
and last night.
She
went BrrrraaaaPPP for the first time at 9pm. What a beautiful sound! Not just
because I wanted to hear it, but also because it truely IS a beautiful sound.
Somewhere between a deep growl and race car whine it spoke of power and
precision. I'm looking forward to hearing it again today - this time I'll turn
the fuel pump on so I get more than 6 seconds worth. :)
The
problems were -
1.
Crank Angle Sensors too far away from trigger wheel - added a thin
washer
2. CAS
wiring reversed - pulse should be positive as you approach quickly with
steel.
3.
Cranking voltage/speed too low
4. And
the winner......12v supply to lead coils suspect. It tested as 12V, but the
plugs wouldn't spark. When I cross wired to the trailing coil supply the plugs
sparked. I thought volts were volts. Apparantly not.
Many thanks to Tracy for his instant availability, patience and
encouragement.
