By asking about the relay are you getting at the pump won't run?

Best way to check it is to unhook the air line and run it to a pressure gauge. I have a vac/press gauge that only shows 10psi. A quick burst from the compressor should put it past 10. Then walk away for 30 minutes and see if the pressure held. If so, compressor is good.

Next up would be airlines and struts, typically struts.
