Truck Repair: 07 ISX CUMMINS AIR PRESSURE

Question
JEFF, I HAVE NO AIR PRESSURE. IT WILL NOT BUILD UP PRESSURE. I HAVE REPLACED THE GOVERNOR AND THE DRYER FILTER. ANYTHING YOU CAN HELP ME WITH?

Answer
I can almost bet you need a new compressor had the same thing happen before wouldn't build up pressure when i would put my hand to the compressor outlet it was pumping air but as soon as you hooked the line up and try to get it to build would'nt do it. Replaced compressor and fixed it.
