Land Rover Repair: air suspention, ecu, dashboard

Question
I JUST BOUGHT A 97RANGE ROVER , DOES NOT LIFT UP , CAN YOU GUIDE ME ON HOW TO CHECK IT, TO FIND THE PROBLEM AND BUY THE PARTS

Answer
First is it a hard or soft fault- Does the dashboard say "EAS Fault: slow 35mph max" ?

The easiest way to diagnose is with a pigtail setup to override the electric portion of the system.  I have full instructions on my website

Use that to determine if the compressor works, and if the bags will hold air.  Depending on what you find you will need different parts.  If you have a hard fault you will need to re-set the ECU as well
