Most likely in tank check valve is leaking or belt is slipping. Belt tension easy to check, should not deflect with thumb pressure. Check valve should not let air escape out of tank. Easy to check. Run compressor till pressure builds to around 50 psi. Then unplug machine from power outlet. Listen for air leaking out of tank. In bad cases, air will actually leak out of intake filter. Replace check valve as needed. Good luck

The trigger valve has failed, replace the orings that are made of vinyl within the valve or replace with new. Also check within the nailer for failed vinyl rings. There could be at least 5 bad orings. The bad orings will be yellow in color and feel putty-like. The black buna rings are usually ok.

The regulator switch/unloader is bad or out of adjustment. Perhaps though the gauge is faulty. 200 psi in a 120psi compressor is dangerous, don't run it until it is fixed!

while I have to say I am not a dewalt guy, I can try to point you in the right direction, assuming there are no leaks, then you state the trigger is not engaging , could be three things, one the trip ( safety) or the trigger valve or the trigger its self, if you feel comfortable pound out the pit that holds the trigger in. Just the trigger not the valve, then activate air to the gun, press the trigger, if it fires its the trip or the trigger rocker switch. the trigger can be examined see if its damaged bent or cracked, see if the safety trip is out of adjust, if it doesn't fire it could be the valve spring inside the trigger valve is broken. don't worry just watch how it comes apart and remember you cant make it worse. it doesn't fire now. anything is an improvement
