Question edited for full 'year make model' in that order.
Question moved to correct category.

Service manual in the link, but for your electrical problem, you will need a mobile auto electrician with a pro grade scan tool computer to diagnose the issue.

Sounds like your solenoid is going bad... easy fix..

Here’s the thing... Rotary Engines are Very Delicate... I Would Suggest Disconnecting The battery for an hour then try again... or get a jump and let it run... should do the trick

Sounds like your battery is just too dead, has enough juice to light up the system for a minute but cranking drains it and if it wont charge then deff fried, you could try removing the battery and starting the car with cables to confirm the starter still works. If a bettery is too dead then when you are jumping it, it takes to much of the power just trying to get through the battery.

Is battery charge ok? Try to replace battery or charge it from other car.

You say he removed the fuel pump fuse? Do you mean he changed the fuse? The fuel pump can't work without the fuse. Perhaps the fuse is blowing and causing the engine to stall and not restart. Find the fuel pump relay and swap it with another relay of the same type. Make sure the fuel pump fuse is good. If the engine starts, drive it around close to home until you think it's had time to stall out again. If it down'nt stall this time then the relay is bad and needs to be replaced.

did you manage to fix this problem as i'm having the same problems. the car had a flat battery so tried jump starting it but no luck, replaced battery but can only get headlights/windscreen wipers/passenger window and hazards to work. car won't start and alot of the interior controls are dead, i've checked fuses (replaced 2)

I was driving my rx8 earlier, and it just cut out, its never done it before, i tryed jump starting it but nothing happened. the battery isnt dead because the radio is still working, could it be the spark plugs ? could that stop the car from starting?

same thing happen to my truck when i needed to jump start it what i did was take of the negative put the key in the ignition dont turn in on all the way just so the power will be on when you connect the negative back on
