The list of reasons could be endless.
Is this a new install ? Is it wired correctly ? Are you getting a stable rpm reading with the software when cranking ?
You dont mention what coils you are using ? Easiest answer there is ensure they are wired as per instructions

Coils are grounded via the harness. You should have a large ground that plugs into the ecu and runs straight to the battery. There is another ground (maybe 16 gauge) that should be grounded to the engine near the coils
Did you ever figure out what was wrong?
I wasn't getting spark or injector pulses, then I switched the A and C pins on the cam sensor extension (running a 6.2 where an LS1 was) and now I get pulses but still no spark.
