I have a serious problem with my Peugeot 407 1.6 HDI I had a change of engine thereafter battery not reported in the table after the starter no longer launches when I diagnosed by the time I see all the parts of the cars except the engine computer when I disconnected the battery I reconnect I see the ABS computer when I put the starter it turns normally live

If diagnose no communication with engine ECU then no +12v,ground or can for ECU
Check fuses in engine bay and electrical wiring of engine
