e46 wagon crank no start

Hey everyone on here. I'm new to the bow world. i always loved e46 and i finally got a 2000 e46 325i wagon with an automatic transmission. I'm here to really need. i got a running donor 2002 e46 330i sedan with a 5 speed manual. i wanted to swap everything over to the wagon which i did. so far i swap 330i motor, manual transmission, rear diff, driveshaft, engine harness, 330i news, ket tumble and body eco. but I'm having a problem crank no start issue. it sounds like its not communicate with the ecu and can't hear the fuel pump prime. I'm lost at this point i try calling shops to help but they would not be able to cause this is a big project. so if anyone did what i did and had the same issue please help thanks

If I understand your post correctly you took a 325 automatic car and swapped in a 3L/5MT? You used the DME, EWS and Key from the 3L car, also correct? The condition you have now is it cranks but does not start? You saw the 330 run and drive, correct?

Do you have any faults?
Do you have fuel pressure?
Do you have spark?

Those should be your (3) main causes for what you are seeing. Start there and report back.

Lastly, you may think about putting the automatic final drive back in the car. The gear ratio is a bit shorter and will give you a sportier driving experience with the sacrifice of a little fuel economy on the highway.

Doesn't seem like you swapped over the EWS. You can't just swap ECU's.
