More then likely it's a problem with the vent valve solenoid for the evaporative emission system .
Evaporative emission system

Image: pinstake.com
The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.

If you were to wait a few minutes and try to add more fuel, would it take it ? Sounds like the main vent for the tank is blocked.

On your key is a diode. Ohm test it . Your ignition is expecting to see that ohm. You can try to reset it by turning key on( no crank) for 10 min. Then turn off and repeat a second time. Then try to start,might work. 2 options replace ignition ( not so cheap on this model) 2nd option ohm key and build resistor to match. On steering column there is an orange wire going from column to bottom corner of wire harness above drivers
left foot. Inside that orange wire are 2 white wires. Cut and wire in resistor to the white wires on harness side not column side. System bypassed, now you can make a dollar copy of key not the 50$ key from dealer and never have the problem again

2000 Cadillac Deville DTS 4.6L HO Northstar

Well, I don't think so. The pressure sensor will throw its own code (0450, 0451, 0452, 0453, or 0454). And likewise, the fuel level sender or sensor could also throw its own codes (P0460-P0464).

I'm not sure the level sensor and the pressure sensor are linked together. They are separate on a 2005 buick century, the pressure sensor being at the top of the tank located on the fuel pump module, but Cadillac: anything is possible.

Since you replaced the purge solenoid, there may be a problem in the circuit. The purge should have battery voltage to it with the key on. The ECM will ground the circuit internally when the purge is wanted. One symptom of a purge valve that isn't working or stuck closed can be a whooshing sound when the fuel tank cap is opened, indicating excessive pressure in the tank.
A shop's scan tool could be used to command the purge valve on to check it.

Gas Overflow

Sounds to me like a bend/kink in your filler neck, or someone stuffed a rag down there.

Remove the fuel filler cap and run a long, rigid wire down your filler neck - if you encounter significant resistance, remove the filler neck from the tank and investigate further.
