Mains powered nail guns with adjustable power contain some electronics and there is a safety switch that prevents operation unless the gun is pressed to a surface.
The design, if not the quality, is common to a host of brands and price ranges, many and possibly all made in China and label engineered.
Using a large electromagnet to drive a nail or staple is an electrically "noisy" method as the coil generates a large back emf that if not adequately suppressed could destroy the control circuit. This could be what has happened due to the probability of the electrical components used not being first quality branded devices but locally produced generic devices rather unsuitable for highly stressed circuits.
Just a guess you understand, it could be the safety switch or the coil or even just a broken wire or a "dry" soldered joint.

On most all nailguns when the trigger is activated air pressure is released from the headvalve causing the headvalve to open and fire the piston. If air leaks through the headvalve orings or through the headgasket port to headvalve, it will not fire. Try applying light grease to headvalve orings and make sure that headgasket is sealing around vent hole. If it fires then replace orings in headvalve for long term repair. Secondary problem is worn safety parts and trigger or trigger pin. If these parts are worn the trigger will not push the trigger valve pin all the way in when you bump fire the gun. With air supply disconnected, apply pressure to safety while depressing the trigger and check thet the pin is moving all the way into the trigger valve. Adjust or replace as necessary. Enjoy

problem solved.whoever had used the tool must have hit something hard because the drive pin had been pushed back just enough to stop it from cycling.

Porter cable makes a number of brad nailers (18 gauge) that very quickly suffer from the problem that you are having. You did not mention the model number of your gun but if it is one of these, (bn125a, bn200a, ns100a) kit # 60061 will fix the problem. It costs between 25 and 30 dollars. Google that part number or order from www.dewalt.com. Dewalt owns the porter cable brand. Before you order the kit, check that the driver blade is not bent and stuck. The driver should travel freely down the cylinder. When you install parts, use Danco silicone grease to lube (availabel at Lowes in the plumbing department) If your model # is different from those mentioned above, please email me and I will recommend a repair.

I solved the problem. I took the nailer outside and plugged it into the outlet on my electrical post. It worked perfectly. I was not getting enough power from the outlet I was using in the house.
