In my mind, running on starting fluid indicates that all other systems are functioning b/c spark is present, just not fuel. If it's proven not to be CKPS then get a noid light to make sure the injectors are firing. Beyond that if they sat for a long time they may need cleaning however I think you'd get some amount of combustion even if it wouldn't start proper.

sounds to me like this may be going on:
(from rave manual)
Someone else correct me if I am wrong, but can't the BCU/ECU lose sync and cause this, requiring a nanocom or similar tool to re-sync them?

Anti-theft system
The BCU uses the driver's door key lock and unlock switches to activate and deactivate the security system. The
driver's door lock is also used for entering the EKA.
+ ALARM SYSTEM AND HORN, DESCRIPTION AND OPERATION, Description.
Immobilisation
For immobilisation, the BCU disables the starter motor relay. When the engine is cranking, the ECM looks for a coded
signal from the BCU. If the signal is not received within one second of cranking, the fuel supply to the engine is
stopped and the injectors are disabled. This also prevents unburnt fuel from entering the catalyst.

Extinct is on to something here...if you jumper the fuel pump and it starts/runs, it is NOT what I stated above (or shouldn't be) as the imobilizer kills the pump AND the injectors. but if it still doesn't start/stay running, then might be what I was getting at...good test to narrow things down even more!

I have never had a BCU/ECU get out of sync, however you do need to sync the interior fusebox to the BCU/ECU. Have you changed any of that recently? Or perhaps the fusebox has failed.

I haven’t changed it out however the car has been sitting a long time w/o battery how do I sync those? I didn’t know that was a thing
