BMW 745i 2002 Fuel Pump Issue

I have 2002 BMW 745i in my shop with start issue no power going to fuel pump
I scanned it with ista/d and it showed no error in b pillar satellite (sbsr)
when I activated fuel pump with ista still no power to pump but no error in module .
wiring ok ,when applying power to pump with probe car starts.
is there any fix for that module or does it need to be replaced ?
