If you have a multimeter:
Ensure your battery has charge. Remove the motor, set multimeter to voltage and measuring between the two motor leads. Ensure nothing being shorten. Connect the battery.
You may see a moment of some voltage when you initially connected the battery, then the multimeter should read to close to 0 volt.
Then pull the trigger.
On a normal working gun you should see the voltage reading almost the same as your battery voltage. If not then you have a problem in the electrical/wiring part, in your case, maybe the MOSFET.
If the voltage is normal but the gun do not cycle, check the gears and mechanical parts.
