Default Raise air suspension without engine start

Hello all - I have a 2004 XJ8 (X350). Car has been sitting for about a year and suspension is sitting at lowest point. I need to move the car but the engine will not start (separate issue I will address at later time) Is there a way to run compressor or air up suspension in this situation? Any help greatly appreciated.

You can put a 'jumper-wire' in the relay socket connectors.(3/5 or 30/87) I would get a power supply to the battery while performing the 'compressor-run'.

Just run the compressor for a while and then let it cool for a while.
See if the suspension responds (KEY ON).
