Possibly the fuel pressure regulator has failed. Pull the vacuum hose off of it and ckeck for the presence of fuel in the vacuum port (indicating a failed diaphragm within the regulator). The lack of fuel dripping from there doesn't necessarily mean the regulator is still good. A pressure test at the fuel injector rail is the real test of regulator function.
