No start 4.8

2002 Vortec 4.8 w/ modified factory harness & Painless Performance ECM flash.

I've got spark, I've got fuel at the rail (haven't confirmed injectors firing) and I've got oil pressure. No 02s hooked up
While cranking it coughs once per revolution, sounds like.
Injectors have been sitting a long time since the engine was run, so I'm suspicious that they are my problem, but really don't know.
Any thoughts? Likely culprits? Common issues ? I'm going to put a noid light on injectors now & check for power around the engine compartment...
