What causes individual spark test to pass, but then no spark while cranking?

Found car has a resistor in the coil ground causing grounding errors for the primary trigger when power to coils was activated.
---Fixed. Clean signal back.
Secondary trigger hooked up, also clean reading.
- Attempting to get full sequential running.
- Confirm Ignition/injector orderings.
- Try firing order 5-3-6-2-4-1 (stock is 1-5-3-6-2-4 but cylinder 2&5 TDC is first to pass primary trigger sensor)
Trigger log here: http://joof1.dyndns.org/vems/prim_sec.triggerlog
CSV: http://joof1.dyndns.org/vems/prim_sec.csv
CONFIG: http://joof1.dyndns.org/vems/joof_1.1.96.vemscfg
Injectors are wired such that:
EC36-19-->Cylinder 1
EC36-20-->Cylinder 2
EC36-18-->Cylinder 3
EC36-09-->Cylinder 4
EC36-07-->Cylinder 5
EC36-08-->Cylinder 6
Coils:
EC36-36-->Coil 1
EC36-20-->Coil 2
EC36-33-->Coil 3
EC36-35-->Coil 4
EC36-11-->Coil 5
EC36-34-->Coil 6
\emph I am very open to suggestions/advice on any glaring issues anyone notices in my config as this is my first foray into this type of thing...
- One more thing: Can anyone confirm whether or not p259's stay on during cranking if set to minimum rpm of 0?
- I found vems.co.uk/forum post from 2007 saying to invert the output and raise min rpm to above max engine speed; seems unfortunate if is still the case (power to coils,injectors, etc whenever ignition switched to on)?

VEMS installed, 60-2 Trigger wheel.
Primary Trigger Sensor: VR
Secondary Trigger : Hall
6 COP.
Had good luck with VR trigger - nice clean signal.
Pinout Diagram:
This - until DME Relay was hooked up (which provides power to injectors and coils). When this happened I lost trigger signal.
--Investigate tomorrow
