Hi guys , been on this for about 4 days now and I’m getting no where so hoping one of you can help me , Iv got a 2005 ep3 k24 swap with a k100 ecu , my car suddenly lost all power a couple weeks ago , I assumed it was the fuel pump as it wasn’t priming and couldn’t be jumped at the relay , I have since now changed that and the car still won’t start , I can’t communicate with the ecu , it has all power , grounds and signal , all relays and fuses are good , I have also replaced the interior fuse box / multiplex which didn’t make any difference, has anyone has this issue or have any idea what could be wrong , Thankyou in advance

Then you don’t have all grounds, power, or signal, or one of your fuses/relays aren’t working. How recently have you tried the ECU in a different car?

Have you tried to manually power the fuel pump (it would basically involve hardwiring it to the battery)? If the ECU is functional, the fuel pump is functional, and power is circulating, then there is no reason for it not to be working.
