Check the height sensors before you look at the pump. Much cheaper to fix,
and known to fail.

Take out the obvious to email me.

A life? Cool - where can I download one of those?

So it didn't come up when the engine started only after you "wiggled the
relay". Which relay?

> can not hear a leak and it stayed up while engine was running

How fast does it decend? Hours, minutes? The exhaust valves in the
compressor box will drop it in a few tens of seconds but you can hear
them.

If the compressor is working a lot it soon will be knackered. They have a
reputation for not lasting long once the system develops a leak that shows
itself with a lowered suspension. They ain't cheap so try and find the
cause. Could be a wiring or relay problem and the height sensors have
already been sugested. Google back within the last year (maybe two) for a
thread about replacing the height sensors. In theory it requires testbook
and some spacers to recalibrate the computer.
