I just replaced the suspension compressor and now it runs constantly. The shutoff switch will not even stop it, nor does pulling the fuses associated with the suspension system. Need ideas of what could be the issue.

You will need a wiring diagram to see how this is hooked up. Have a technician diagnose it for you. Most likely you have a power line shorted directly to your pump bypassing relays and air suspension fuse. Or you may have a leak in your air suspension lines and air strut continuously running your pump.
