As suggested by Chuck, time to recheck control pressure.
Cold pressure should be 22-26 psi. "Cold" = 68deg. F.
The gambit of cracking the injector line nuts on the FD is a good starting point for a check of flow to the injectors. If there is flow at all the fittings, the next step is to remove all the nozzles, reconnect the lines to the nozzles, and place each nozzle in a separate container (soda bottle). With the pump running, pressing down on the air flow sensor plate should produce a spray of fuel from each nozzle, and the discharge from each should be equal. The cracking pressure for the check valves in the nozzles is about 40 psi.
