2001 9-5 V6 Cranks But Won't start
 

I really need some help. 2001 9-5 with V6. 120,000 miles.
Car ran great. Parked it. Next day cranked but wouldn't start. Sat for almost 2 weeks. Car started. Ran for two days then stranded in parking lot. Crank but not start. Towed it home. Replaced fuel pump and filter. Noticed oil in plug holes. Replaced valve cover gaskets, plugs, and DIC's. Replaced Crankshaft position sensor too. Still cranks but wont start.
Car will start if I use starting fluid so I'm thinking fuel issue not ignition. Don't have a pressure gauge but there is fuel at the schrader valve.
I've heard the fuel regulator very rarely goes bad but could that be the problem? Any other thoughts?
