Also check wiring to and at the injectors. On a fresh new build I had fuel to the rail, knock you on your butt spark, what I thought was clicking injectors but wouldn't fire up. 99.9% time I can just reach in and turn the key and they fire. This one (my own car of course) labor went on for two days. Everything looked fine, one time playing with the connector at the injectors I got intermittant clicking. Found wires broken but insulator fine. Code checker was inconclusive. Repaired connections and it started on first turn.
