Hey guys I had my pump replaced a few months ago and when I got the car back the ABC light would come on when I hit a bump, and now it is dropping down to the right side, the stealer told me that the pump isn't putting out enough pressure but they couldn't guarantee this would fix it. my pump is a reman and where I got the pump they don't want to cover the labor cost to put in a new pump -- any ideas what it could be, to me it doesn't seem like a pump issue because the car is dropping down the right side after it sits parked overnight
Any ideas?

2 different problems you have.
When you hit a bump and you get a warning chime for a second it is one of the accumulators going bad
When the car lowers itself when parked it is the valve blocks gong bad.

is there a DIY for replacing the front valve block? I'm drooping on the front drivers side. the light will come on. I just restart the car and it goes away. but, this will definitely become an issue. I saw a diy for the back valve block. wow! there is very little room to work on that.

There is but I think it was on the CL forum. Do a search.

so your not buying the dealer telling me that I need a new pump or the current one isnt putting out enough pressure?

the car was in a accident with a front right impact - that is the side that is dropping down when parked - the front right and right rear side drop down to about the wheel well when parked overnight - the driver side stays normal - and when I hit a small bump the red light comes on and then goes off ?? im lost and i dont think the dealer has a clue either.

1) agree bump issue is the accumulator, see post #73

2) dropping overnight.. is that only 1 corner? or front end? or back end? might be block.. but maybe also a leaking strut.

Explain of cleaning the block:

An alternative.. is simply flushing the ABC fluid+rodeo while changing the filter twice. Some people say this works and cleans the block on its own.
