I got this car that doesn't start after the radio was taken off, I have tried multiple stuff without success, the fuses look good, tried different connections with wires, jumping the battery… and nothing. idk what to do anymore Id appreciate any help on the matter please! Thanks

I would start by insulating these cables. Separately.

First, get those exposed wires taped up. Old Citroen electrics are super touchy, and crossing a wire could easily trigger the immobilizer. If you still have the original radio, plug it back in and see if it starts. If it fires right up, that pretty much confirms the system is locking you out because the immobilizer module is missing.
