No Air pressure, plz help

Go to parts store buy AIR press. reg. it will be less than 40 $ and all will be back to normal.

 

The first thing I would check is the air governor. It is usually located on or near the air compressor. You can usually hear air coming from it if it is bad. You can buy them for about $12-22. If that is not the problem you might check the air dryer. Once you locate the air dryer see if you can hear air coming from the bottom. You can stick you hand underneath and see if you can feel air leaking. If so, there could be grit preventing it from closing. It might also need the filter changed. The last air dryer I bought cost about $345, as I recall. Another thing to check would be pressure release valve. It should be on the side of your air compressor. If it is bad, you should be able to feel air coming from it. Those valves, sometimes called "pop off valves" cost about $45. At least that is what I paid for my last one. These don't go bad very often. Once the pop off or release, you will need to replace it. I would suspect the air governor. It is the least expensive thing to replace and is the most likely thing to fail. Other things you might check are other pressure release valves. You should have those on your air tanks.

 

You could take an air line loose and see if it is pushing air through the line. From your post, I don't think it is the air compressor. I usually start with the most obvious or least expensive thing to repair and work my up to the most expensive. The compressor would be the most expensive repair. As I stated, my guess is that the air governor is the most likely culprit. I have had air governors fail and they simply won't build air when they go bad.

 

It looks like your air compressor is working since you could build up air to 30 psi. like previous guy said it looks like your air governor is bad. Very easy to replace and also cheap. Located on the driver side firewall left upper corner.

 

check the footvalve as it can go bad or get dirt/sand in it

 

Governor is mounted on the firewall, drivers side,top corner, as posted IIRC
