hate to ask you to do this but suck on the source vacuum to the regulator...it should let fuel flow~ if not we have a defector on our hands~

I'd look at the fuel pump, unless you can hear it runnin'~

there is a fuel pump relay as well~

CHECK FUEL PUMP PRESSURE AT THE FUEL RAIL ALSO TO MAKE SURE IT IS IN THE PROPER RANGE AND IT NEVER HURTS TO CHECK FUSES,RELAYS AND CODES ON THESE OBD II EQUIPPED CARS.. RAGONZALESSR
