So I have a 2003 BMW 325xi and it keeps dying on me during heavy traffic and it runs rough at idle and some times on the highway when I try to pass someone it doesn’t have any power. It even holds gears sometimes when I drive on the street and highway. I put a code reader on it and it said that I’m running lean and I have misfire on all of the cylinders except 3 and 6. I checked all of my vacuum hoses and ran a smoke test on it and nothing wasn’t damaged or leaking, I’m lost and I need help finding the problem may you please help me. I also checked the spark plugs and coil packs and they are all good.

- 2002 330ci I am getting readings 1. fuel injector off 1-6 2. clock fuel injector 1-6 What does this mean? Injectors and fuel rail were removed when changing intake manifold gasket. When I google "clock fuel injector" all I get is the definition of fuel injector. Any help will be appreciated.
I bought a 330ci that had been in a minor accident (front end). I was told the fuel pump needed replacing and I did so. There is no power to the new pump and it cranks, no start. I checked fuse in ECU box and changed relay. The main code I get is 50B - MRS battery positive terminal isolation 1 and MRS power supply.
Hello there is a fuse on the positive battery post , its called the ibs, I can't remember if you can reset that one or if you have to get a new end
@BMW Workshop Thanks for the quick reply. Everything I researched on ibs indicates a no start - no crank. It is the same with the explosive disconnect on the hot wire ( no start-no crank ). When it warms up a little ( unseasonably cold in Oregon ) I will try to disconnect and bypass. This car cranks strong - it seems to be not getting any gas. There also seems to be a comm. problem with the ECU. The comm. box was crushed during the accident an needed to be replaced. There is 1 wire coming from a small harness that I am not sure where it goes. I will post a picture later today. Thanks again for your help. I think it is great that you started this forum :)
Here are a couple of pics. The unknown wire is the one with the circle connector. that comes out of the harness that goes into the ecu box
