Default Generac 990 16kw Standby Generator

Hi to all, my 16kw 990 lp gas generac generator won't start unless I either manually open the lever in the regulator behind the diaphragm or give it a squirt of quick start in the mixer box. The generator will start and run perfectly when it starts. The generac tech said it was a bad regulator which I replaced. The fuel pressure is 11.5 in/H2O with the engine running and maintains it with load. The tech is telling me the new regulator is faulty. Does anyone know of a test to open the regulator before I purchase another one. Any help would be appreciated.
