FWIW there is no gas cap code. There's evap leak codes. Gas cap is the most common, it seems like you may have a different issue. Please post all teh codes and names.

^ This.
It sounds like your evap solenoid is stuck open, not letting the system build pressure when it needs to.

Before you run off and work on stuff that isn't broken, would you please post all the codes and their descriptions. Then we can help you aim for the right things.

The only code was P0455, am I missing a secondary code?

Sorry the full message is " P0455 Evaporative emission (EVAP) control system leak detected(no purge flow or large leak)"
I think it might be the evaporative canister??

I had the same code on my 04 gp. I made the mistake of buying a new purge valve for about $45 when that wasn't it. It turned out to be the wiring to the Evap Canister. One of the wires was torn almost all the way through.

If you have already tried a fuel cap your next step would be to smoke test your EVAP system to see if there is a leak anywhere.
You can visually look under the car if you'd like. see if any of the hoses look damaged. short of that i would get it smoked to find the leak. i believe the canister is close to the fuel tank. diagram below
1.fuel feed pipe
2.evap purge pipe to engine
3.fuel level vent valve
4.fuel tank pressure sensor
5.fuel filler vent pipe
6.canister vent valve
7.vent pipe to canister
8.modular returnless assembly
9.evap purge pipe to canister
10.canister
