electric air pump doesn't seem to be working

check fuse and relay for this, but you may have a bad pump.

what is the name of the pump, and what system is it? why does air tube go through firewall, and what does it control?

it controls the air ride suspension in the rear.

this is the level ride compressor.does the level ride come on the dash?it has a test wire right where the harness is.youll see a wire by the compressor not hooked to anything and maybe taped back. it has a green connector on it.turn the key on and ground that wire.the compresser will start running. we will start here.addReply to Question

I know this is old post but only link I found to my problem.
I jumped green wire. Pump runs but only when I do that.
What does that mean? What needs to be replaced?
Also I left it running and found it does pump air but guessing leak somewhere.
What can I add to line that will escape leak hole and show itself without damaging the system?

if you have a leak use soapy water around connections and shocks to find leak . and do as I said in first reply

I can hear where the leak is but have no luck stopping it.
The hose going into black canister at compressor leaks. When I remove hose and plug with finger it holds pressure. I hook up hose and I can hear air escaping. Have to create a small reservoir to hold water so I can submerge the area. Spraying it didnt work but I can easily hear it and know where it is.
The line is so small in diameter. Is there a way to cut it and put new end on it for better fit? It is a plastic air line with plastic compression fitting on end. Two small washers on backside of compression end.

they shold have them at auto parts.
