Due to a faulty vater pump busting the engine I'm doing an engine swap in my 316i compact.
From the standard M43B16 to a M42B18.
I'll try to write down as detailed as possible:
The car is an 316i Compact -95 and the donor car is a 318Ti Compact -95
The engine cranks, have spark and runs if applied starter spray.
The fuel pump relay never draws, It have power and is not faulty, I've tried swapping it out 3 times, so either I'm having extremely bad luck with 3 faulty relays (that i know have worked before) or the relay never gets a draw signal. The cabel between pump and relay works and appling power directly to the pump makes it pump. So the pump is not faulty.
I've tried reading the motor codes with inpa but I get a "control unit not found" error. Also the Battery and Ignition indicators in inpa behaves very strange, battery not connected: Inpa shows battery on, ignition on. Battery connected: battery off, ignition on. battery and ignition: battery on, ignition off.
I've ordered a TinyADS interface and digging up an old laptop to create a better fault checking setup since now I'm using a cheap china reader and running XP-sp3 in virtualbox.
A stomp test gives nothing and the check engine light never lights at ignition. The DME has constant power and gets the ignition on signal.
Both cars had EWS2 but if it was the EWS acting up the car would never crank, right? I've tried swapping the DME between the cars but with the same results. I never saved the EWS2 module from the donor car.
The only thing I haven't tried so far is to swap the fuel lines under the car, it could be that I messed up the order.
So, does anyone have any ideas?

Get and run EWSsync.

I don't think you need tinyADS. Here is a newer version of INPA that is more OS compatible.
