02 Rear Air Suspension

[BlueBravada]

I have an 02 Bravada with the rear air suspension. Suddenly it won't inflate. With key on-engine off there is a short delay and then the pump comes on but then shuts off again after about a minute and the vehicle is still sitting too low. The pump will not stay on long enough to raise to the correct height. I've checked for leaks, none found. I've check both height sensors, they check OK. I've even tried a different pump assy (used), no change. What else is there?

So if this helps at all?
