sounds more like ecu fault. did problem start after doing immo off?

i fitted a second hand ecu did the immo off ,but the same fault was on that ecu as well after starting up ,deleted faults and came back after 1 week.

Check wiring in engine bay,especially from CKP and injectors and measure injector coil resistance.
