    I parked at the truck stop last night, got up this morning and when I cranked the truck I have no air going to my trailer. I checked all the lines, do not hear any leaks. Disconnected the lines from the trailer. still no air.
    There seems to be no air supply coming from my air compressor to the lines. Parking brake & trailer brake will not push in/apply. Any ideas on what might be the problem?

    You said no air to trailer, then afterwards say no air from compressor, which is it? Do you have system pressure in the first place?
    If their is no system pressure, and no leaks, the first place to look is the air governor. It's also the cheapest and easiest to replace from $10 at the parts store to $75 at the truck stop. It looks like this usually.
