1997 BMW 318is Base 4 Cyl 1.9L - Engine
My engine broken a connecting rod bearing. I replaced the engine. The replacement engine will not start.
The first time tried to start the ground wire for the fuel pump relay burn. Using a code reader/rest tool showed battery disconnect. Before no spark to plugs, fuel injectors not working, and no fuel pump action. Now the engine check light come on, before I change the engine harness. I replaced the whole engine harness. What is my step to get this engine running.
