    Check that the compressor's getting power and hasnt blown a fuse, has a short, or corrosion (- and + wires).
    If you got power to the compressor check to see the compressor isnt burnt out.
    And check to see the compressor pressure sensor is working correctly.

    Ebay or McMaster-Carr ( has several to choose from in different pressure settings (on/off). Maybe check your local hardware store or a shop that installs air bags/air ride in vehicles. Did you have the old one mounted upside down, by chance?
