This is the fuel press spec from a gm service manual. Key on, engine off. fuel press with pump running and air bleed out of fuel press gauge (remember eng. off!!) is 55-62 psi for eng code "t" for eng code "z" its 48-54 psi. Look at the 8th digit of your vin for the eng code.
Fuel pressure for 02's according to VIN:
(55-62 psi) VIN: (V, T,U)
(48-54 psi) VIN: Z
Check the pressure as soon as you turn the key to run. It may drop a little as soon as the pump shuts off. With return-style fuel systems the pressure will be 8-10 psi lower when it is running depending on your engine vacuum. If you pull the vacuum line off the fuel pressure regulator while idling you should see the pressure rise by this amount to the specified value. You may have a problem if your VIN T pressure is less than 45 psi at idle or 55 psi when not running or with the vac line off the FPR. I would check the regulator first if this is the case. Make sure there is no fuel leaking out the vac line connection.
