BMW X5 V8 4.8i ecu no start, how to solve with Galletto 4 v54

I have one big problem with BMW X5 V8 4.8i ecu, the car no start. Starter relay and fuel pump relay turn on-turn off-turn on-turn off-turn on-turn off (intermittence synchronize between two relays).Battery is Ok. Ground connections from engine is OK. Strange it fails. Scan tool not recognize.

ECU flashing tool I use:

Galletto 4 V54  I can read flash and micro with Galletto with BDM mode.

Pin out for this BoschECU…
looking from the left: as the above pictures…
Socket 1st:
pin_7 and 8 +12v
pin_4,5,6-grnd
socket 4th:
pin32-_diagnosis
pin36_CAN-L
pin37_CAN-H
pin26-+12v
socket 5th:
pin5-grnd

Finally, solve!!!

Read points with BDM system. (Read with Galleto 4 v54) For security verify correctly ground pin position.
