I have replaced the starter and battery. I have power to the starter and have power to the starter post when trying to start. I have not tried the transmission cable connection or relays or fuses. It cranked before the engine swap. I put basically a 528i engine in a 328i. Any suggestions as to why it wont crank or start. Lights power on and bell dings when I open the door. Appreciate any help. I have exhausted my pay grade of knowledge.
