Hello;
It sounds from your description that the fuel pump is weak. To check the fuel pressure you need a fuel pressure test gauge for fuel injection. Attach the gauge to the test port schrader valve and turn the ignition to the on position. Record the reading. Now start the engine and record that reading. Unplug the pressure regulator vacuum line and record the reading.
The pump should have pressure with in specs but if low, start with the installation of a new complete pump. It is located in the fuel tank. Also replace your fuel filter.
Hope this helps you.
Thanks;

first check the fuse and relay for fuel pump. heres how to check the pump. get under car and put hand on bottom of fuel tank, then have a person turn key to on . if pump is ok. you will feel a vibration in tank. you may have to do this a few times because a fuel pump only runs a few seconds to get fuel pressure to engine then shuts off. but when vehicle is running its on all the time to supply fuel to engine.

Fuel Tank - 19.0 gallons

Break Fluid - DOT 3


Rear Axle Lubricant - Motorcraft 80W-90 Premium Rear Axle Lubricant 3.75 pints (add 4 oz of Additive Friction Modifier C8AZ-19B546-A or equilavent meeting Ford Spec. EST-M2C118-A for complete refill of Traction-Lok Rear Axles)

Engine Data - 4.6L V8 Engine
Cubic Inches - 281
Required Fuel - 87 Octane
Firing Order - 1-3-7-2-6-5-4-8

Engine knock 1999 ford crown vic


Are u using the recommended fuel ? if so try running a couple of cans of fuel injection upper cylinder cleaner through the system with the next few tanks of gas, try LUCAS brand, it is among the best, the next step is to have the engine de-carboned by the dealer, this works very well, you can also remove an octane selection jumper, it retards the timing 2 degrees, that will most times stop the ping.
