    m54b25 wire problem..

    Hi, I am switching the engine of my E30 to a m54b25Ci, until all, everything has gone well. So, the other day, I tried to start it without pouring. After a little search we found that the nozzles did not deliver gasoline, but there is pressure in the nozzle bridge. Since then, I have borrowed a BMW Scanner from a friend who, after several tests, finally got connected to my DME, luckily took some pictures of the errors because now I can not connect to the more, what can be the reason for that ? Have checked wires and connectors to the best of their ability without finding anything I thought was suspicious. In the case of lack of gasoline, I have found that I lack a relay for the fuel pump / nozzles, only the 2 have been seen in the picture. is that really understood? Hope there are some wise who can help me on my way, got a little overcome because of these problems.! I connect via 16 pin OBD2. Please inquire if I need some info.


    Regards Patrick :roll::roll:

    The only code that matters is the one for the relay. probably, it's just wired incorrectly, or you have the wrong relay installed.
