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.
Hi all, I was driving down the road the other day and the car died at a stop light. I tried to restart, car cranks over but would not start. My first thought is that the fuel pump died, but when going through Nathan's Youtube channel I saw a video that suggested a fuse in the ECU box may have blown. I checked the fuses today and all the fuses were fine (30amp & 20amp) but I replaced them anyway. I tried restarting the car but got the same result, crank but no start. Electrical in car seems to work just fine, lights, radio, obdii, etc.
FYI, ECU reads clear, no errors.
Anybody got any other ideas before I start ordering fuel pumps?
Thanks,
I would say fuel pump
Yes, I think you may be right. I just need to check for fuel pressure and that will confirm that. Was hoping maybe it would be something else.
