eas again

a friend of mine had faulty compressor pump so fitted new one and at same time replaced all orings on block and now all back together pump runs but no lift is there seems to be air in tank so my question is where do we look now for maybe pressure switch or non return valve if these can they be tested or am i on totally wrong route

oh and eas is unlocked

thanks for looking

Open driver's door, and allow the pump to run until it shuts off. Then the tank is full. Close all doors, and it should start to rise.

If not search, read & study the 100's of posts about exactly this problem.

Have you disconnected the blue pipe from the compressor and tried to hold your thumb over it, if you can compressor is not making air, did you have the door open st start with this will stop the system trying to rise till the tank is full which can take quite a few mins then when pump stops close door and it should rise.

If no joy have a look in the technical archive, top left of range rover page for the post by the late Wammers on the eas system and follow the fault finding checks

tank was full of air and did close door but still no lift in bags at all its as if tank is full but not opening any solenoids to lift it up
thanks for quick reply

Are you sure all the valve block solenoids went back in the right places

i wasnt there when he replaced them but will check tomo as im going over to have another look but he is normally meticulous so would have thought so
