Does the Presta valve adapter have a valve core depressor? I want to know is whether a pressure gauge attached to the chuck will show tire pressure

Yes, this can function with gauges and inflators as long as the fitting are 1/4 npt. Hope this helps.

If i purchase new 2.0 compressor can i attach this chuck direct to compressor hose like i do with a schader ball chuck. If it has auto stop built in.

This Jaco Lightning air chuck does have auto stop. When removed from tire, air does not escape. She threads onto hose for secure fit, using standard teflon tape or putty to seal the threads. Surprisingly high quality product, metal chromed body, not plastic, made in USA. Highly recommended.

I have a lezyne floor pump with abs-1 pro chuck. i am dissatisfied with the lezyne chuck. can i simply screw the jaco onto the lezyne?

This chuck is compatible with 1/4" NPT fittings. We recommend viewing the specs of your current item to verify the fitting.

Will this chuck still lock onto a presta valve if the valve core has been removed?

I use it this way to seat the bead on my MTB tires (Specialized Butcher 27.5 x 2.6''). Since I already remove the presta valve core to add sealant, saves a little time by just twisting on this adapter and knowing ALL of the air is going into the tire. Versus using a blow gun and worrying it may not seat if it doesn't get enough air in there fast enough.
