have the pump tested to be sure it is putting out pressure.

do the air bags drop over night?? if they do, the bags may be the reason for the pump failure

How do I check to see if it's putting out pressure, since only the back is raising now, and yes I did have the problem with dropping over night

dropping overnight is most likely bad bags.

if the system is pumping up the bags on start up. then it is pumping pressure
