Question about Tools & Hardware - Others
Your question isn't specific enough. Multiple things need to work together to fire a gas fired nail gun;
First the obvious user faults;
Nail guide jam
Not so obvious;
Broken/worn return springs (nail guide and firing bolt)
Faulty micro switches
Bent or impacted internal mechanism
Ignition or spark fault
Dirty or damaged ignition chamber (just like a car piston, cylinder and rings)
Faulty micro controller and ignition circuitry

SOURCE: bostich gun problem
If the piston/driver is broken, the gun will fire however nailing will not take place because the piston will jam in the cylinder. Sometimes the cylinder will also crack when the driver goes. If the piston is not broken but stays down, then check the cylinder check valve, worn lower bumper, bent driver or cracked cylinder. 18 guage nailer has a very thin driver which will easily bend or break. Parts however are not expensive.

This is a discontinued tool by Senco but there are still parts available for it. It sound to me that the o rings and possibly the firing valve need to be replaced. I would recommend going to Senco.com and you will find a complete parts diagram in their discontinued tool section. They also have a toll free number if needed and you can talk to their air pro. I have rebuilt quite a few of these and they are not that hard just make sure to clean all the parts and use lube when replacing O rings.

Where does the air leak out from? If it leaks from the trigger DeWalt makes a trigger valve assembly part # 641006-00 list 8.89 BUT if it leaks from other areas we have to look into it deeper. If it is just the trigger valve let me know and I will give you instructions how to remove and install the new one.

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.
The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com
