Default Air Suspension Failure

'90 LS400 266k milies

$2,500 and counting... Since last fall, I've replaced the following air suspension components. Obviously, I would have installed coilovers if I had known want I was getting into earlier.


- New OEM Rear Air Strut
- Rebuilt Rear Air Strut
- Rear air suspension pump (used)

Has worked OK since. This weekend, the entire car dropped.

Assuming that 4 struts and 2 pumps did not fail simo, what would cause the entire system (front and rear) to fail simultaneously? I've reset the control module but the car won't raise.

it was for charles. but i have seen these go bad on a LX and they would either be slammed or high in the air. Could that be the situation here?
