So I swapped an s52 into a e34 525i but after everything was hooked up it will crank but not fire fuel pump wont turn in and no spark or signal to the crank angle sensor. Ive also switched it to obd 1 with intake kit and red label 413. could this be an ews problem? btw this car came with the m20 motor and no ews in it at all. so its closer to swapping an s52 into an e30.

Check the 3 main relays for the harness, EWS should not be a problem with a 413 ECU.
