My Ruger .177 as from the factory about 5 years ago, it has never been tuned, nor given much maintenance attention other than tightening screws and scope mounting. I'll guess it has been fired 1000 times. Today I took it out to target shoot a few and found the break barrel would not latch open for loading. Welcome any suggestions on steps that make get the gun at least back to operating. I do not want to get into releasing the spring so it that is suggested as necessary I may just shelf the gun. Thanks

I do not understand "will not latch open". If you mean the spring wants to push the barrel back to the closed position that implies the gun will not cock. If it will not cock the spring is as relaxed as it's going to get and the gun may be disassembled.
Before disassembly though you can try backing off the trigger adjustment screw. It sounds like the sear is not latching the piston to hold it in the cocked position. You may also have some dirt or gunk built up in the trigger assembly. There is also the possibility one of the little springs inside the trigger assembly broke and is not pushing the sear into position.

Like Roadworthy said, screw in the trigger adjustment screw in. It may have vibrated out.
I adjust my Hawk triggers by loading them, laying them across my lap pointed down range and screw in the screw till it fires then back out one to to 1 1/2 turn. The load it, make sure the safetty works then bump the butt stock off the ground to make sure it want go off. Then blue-lock-tight the screw.

Thanks, sorry I took so long to respond to answers/suggestions. Guess I'm not getting notification by email. I do occasionally get an email for GTA, so my address on file is correct. I'll try suggestions, and the problem is will not "cock". I'll have to check to recall what else happens, but I think there is spring pressure and I lowered under muscle resistance the to fire position. I have not checked to see if it is already cocked, and will try a "dry" shot down range to see if anything happens. Again, THANK!! I'm not a regular here or shooting, I live in NJ, a very unfriendly gun state. Yes, even pellet and even bb guns not to be fired unless engaged is licensed hunting with appropriate weapon (likely never a bb gun for hunting, at least bb these can be fired inside). Yes, one can shoot at a licensed shooting range, imagine going to a range to shoot a pellet gun! One can also hunt and shoot on farm property and while I have a large property it is not large enough to apply for a farm discount on property taxes. Yes, much more than you may need or want to know, but if you are not in NJ you can at least say "thank God, I don't live in NJ". Hope GTA lives on, I participated on "airgunone" for several years, and on a "rimfire" forum for similar time... both are out-of-business.

I would say that there's a good chance your main spring is broken. Those are fairly easy rifles to work on if you have a spring compressor. If you don't want to open it up yourself, Mike Melick knows these backward and forward. I think he charges $100 for a full tune. I would suggest sending along a spring from air rifle headquarters or Vortek for greater spring life. Good luck with it.

Adjusting trigger release through the screw hole in the trigger guard did not fix. Spring definitely is "active". Just checked so my memory is fresh: the barrel has to be guided back as the spring is definitely compressed and pushing back when in the cock position. I assume the compression/cocking compresses the spring to a position where a latch can take place, the latch being of course connected to the trigger. Perhaps some clean with spray cleaner in that area will allow the catch to catch. I also have a nitro Crossman, does it also need a compression tool to disassemble? If I can buy a spring compressor (I have seen some home made devices too, most likely on youtube) and it is applicable to both pellet rifles it could be worth my time, and could encourage me to do a full tune-up.

Jerry, only times I've got a GTA alert on my email is if someone PM's me and then you have to respond thru the GTA PM. Actually I don't get that anymore.

This is a pricey little bugger but looks adjustable enough for about any springer and well-built enough to last a lifetime. Home-made ones work ok though and not terribly hard to build. Good luck with it.

If the pin in the cocking linkage breaks the gun will still feel like it's cocking but it won't go back far enough to latch. It uses a circlip in the center, the groove making a weak spot.

One of these two issues, either one will require taking the gun apart to fix it.
