I have the air ride shocks,how much air should I put in,not pulling anything or any heavy hauling? I got 50 lbs in there now..they were empty.

It'* really depends on the firmness of the ride you desire, or the height you want to ride at, or a balance of the two. I'm assuming here that the car didn't come with ELC?

it has the pump for inflating tires etc.didnt know they had the level contols

Thats an accesory pump shrader valve in your trunk for filling tires. Not for filling the shocks. It does have OEM air ride then. Either the pump is shot, fuse blown, or something with the ELC circuit. Not a guru on this, lets let a gearhead get in here. And get it moved to it'* proper machanical Section. That helps get it noticed.

yea i read the manual about the tire filler,but im not sure about load lvl

i pumped the vavle up to 50 lbs..i have air shocks ..

should i let the air back out of the valve?

the shocks will self level themselves after driving for a mile or so.

to check if your pump is working locate the height sensor in the left rear wheel well. disconnect the rod on the control arm end. gently push it up. in about 5 seconds with the car running the pump should activate. if that happens and the car does not start to raise it'* rear then your air shocks are toast. if the compressor does not come on look in the rear fuse panel under the back seat for the ELC relay and the fuse for it as well. replace and repeat the test

would you hear anything while your driving if the pump is working?

best bet is to start the car and leave it in park with the radio off when it kicks in you will feel a little vibration from the back. also if you start the car and push the air button on the trunk moulding you will hear it kick on.
