Hi
2014 f10 520i with n20 engine . Car came to workshop with tug . Problem is engine cranking but won’t start at beginning no any error code after a few start test ecu give 111030, 111031, 111032,111033 cylinder no1,2,3,4 fuel injecter current increase very slow . I checked ecu one electronic components broken as photo and replaced and tested error code gone but same issue no any error code cranking but won’t start after a few test same components blown . Also have another thing I checked rail pressure during cranking 150 bar same as ecu request but if I release rail pressure to zero and try start engine start a few second but stop again . Checked; injecter, spark plugs, high pressure fuel pump but looks normal . I suspect from ecu I have used ecu from 328i f30 n20 can I use this ecu for 520i same hardware if I change isn? What could be wrong
