Loosen the wire tension er and cram the nozzle into a glass of water. If there's no bubbles when you pull da trigger it's either the trigger or the solenoid.
Make sure your whip is pushed in as far at it'll go and use a lil asz when you tighten that wing nut.If its 1/4" out of position you got no gas

 

Check to make sure the power pin on the back of the mig gun is FULLY seated in he wire drive housing.

 

This ^^^

It's really often that this ends up being the problem.

But of course the switch and solenoid, among other issues, also happens.
So does coming unhooked inside the case, or hose cracking inside the case.

 

People have no idea the forces required to toss a couple hundred amps at a wire(guitar string) surrounded by a little gas and put against a dead short. Take all that stuff apart, clean it up nice, reassemble and you should be OK.

 

Thank You so much, I have gathered some info and will post my results below.

 

Thank You all that responded with diagnostic tips, i truly appreciate the help. So, here is what i did, and i hope that someone else will be able to benefit from my response. I first released the cable tension and dunked the stinger in water, one tiny bubble came up then nothing when i hit switch. That told me i had no gas at the end. I removed and reseated the stinger in the machine, paying attention to depth as well as the electrical plug, all was like it should have been, still no bubbles. i pulled the rubber hose from the valve and put a test hose on it, dropped that hose in the water and have a super amount of bubbles, i replaced the hose from valve to stinger for good measure. So, at this moment i have either bad o-rings on the stinger, or the stinger itself is an issue. I appreciate your guidance, i had no idea where to start and the many kind souls here put me in the right direction. Next to devise a test on the stinger to see if it is somehow stopped up not letting gas flow.

 

Simple. pull the gun from the drive, pull trigger. gas should blast from drive.If so machine is good.
Gun is bad. you can try removing the handles one at a time from both ends and check the gas hose.
see if it is broken or pulled off the fitting inside the handle. This will allow the gas to leak away before
getting to the tip of the gun. Or you can take the hose off the gas valve, insert gun into the drive all the way. and blow through the hose. Might help you find the problem with the gun. Or just replace it.
