Can anyone show me how to rebuild the pump or a how to find out if the pump is really bad. does any one have pics that show me which relay it is and what to look for under the suspension.

BigBadBonne. I moved this into a new thread. To get better service and responses directly to your questions, it'* best to start your own.

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.
