I had a no start issue the other day with my new build. Ended up being two of my 10 month old FIC 1120 injectors were completely frozen from sitting on a shelf for 6 months with WD40 in them...
Slapped the old 950s in and it started right up.
Start with the basics. Check for spark, make sure the timing is spot on & the the CAS isn't 180 out. If those are fine, check fuel pressure. All of those were fine on my car and you could hear the compression so checking the injectors my last piece of the puzzle.
**This is assuming you have the ecu/tune setup correctly and no crazy wiring changes, etc to add to the confusion
