Question about Hitachi Tools & Hardware - Others
The number one issue is bad fuel - even if you just purchased it, turn the cell over and check the date stamped on the bottom (often stores don't rotate their stock)
If the fan starts when the nose is depressed but there is no spark then I would investigate the spark wire (make sure there are no nicks or cuts that may short to ground) and the ESU (Electronic Spark Unit).

Most gasoline engines need three basic things to run: proper air/fuel mixture, sufficient compression, and a properly timed spark. Check the easiest, cheapest things first, then check the "Gee, I forgot to turn on the gas" kind of things next, then work your way onwards from there.
Compression can be guesstimated with the proverbial thumb-over-the-empty-spark-plug-hole routine as you turn it over casually to check compression. If it doesn't blow your thumb out of position, you could have a hole in the piston (overheating response) or a stuck or damaged intake or exhaust valve.
Check for fuel flow by carefully disconnecting the fuel line to the carburetor and letting some run into a tin can (no styrofoam coffee cups, please). It should dribble freely. If not, you have to back-track the line and find out where the blockage is.
Spark is one that sounds like you've already tested (spark plug out of the cylinder head, hooked up and laying on the metal engine as you turn it over?) so check timing. You will probably need a manual for this test, although a good estimate is that the plug should fire just a wee bit before Top Dead Center position of the piston. Like I said, a manual comes in handy here.
From what you've mentioned, though, I'd start trouble-shooting at the fuel flow part first.

You can try spraying some carburetor cleaner into the carb. If it starts for a minute, your carburetor need cleaning. When you added new gas did you remove the old gas first? Is the air filter clean?

Start with the basics:
First check that the butane (or whatever gas is used) canister is full. If empty, put in a new one.
Second check to make sure your battery is fully charged to be able to fire the spark to work the nail gun. If not get the battery charged and/or replaced as needed.
Third make sure all of the safeties are working properly and that you have them engaged to the piece of wood you are nailing when you try the trigger.
If beyond that it does not work it could be a bad trigger, a bad safety switch, or even a bad connection from the battery to the device.
