No Start Citroën C2

HELP! my 2004 Citroen c2 vtr 1.4 does not want to send power to the fuel pump and start

Here's what I've diagnosed and done so far

• Checked if fuel pump pumps on ignition (it does not)
• Used external 12v source directly to the pump and it could start and moved the car around
• Tested the relay and fuses, they were fine but as a precaution I bought another B3 BSM (still not sending power to the pump)
• Tested the cable itself, I could only test grounds and they had continuity, no power to the rear though​

Some more context would be it drove fine the day prior. Then the next day tried to start it up and it refused to start. This started 8 weeks ago and here I am with the same problem still.

Has anyone had the same issue and hwo did you resolve it?
