Installed dual 450s the other day went to start the car ran for 1 second and died logged on jb4 lpfp psi and it ready like 5 psi. Changed ekpm2 to a ekpm3 that I knew worked good on my last car with this setup. Checked fuse, swapped relay. Not sure what else to hit me with some suggestions. Pumps work because I hard wired it and my car ran for 5 seconds with the fuel pressure it built up.

Absolutely zero clue, I noticed I had some grains of wheat in my car I probably had a mouse or something in it they like to come warm up near the motor after the car is parked. They may have done some damage because I was able to log on my jb4 now I am no longer able to all it reads is rpm

Thanks guys. I will never buy another 06 or 07 production date again. I've had nothing but wierd electrical issues and so does my one other friend with a 06 production date. Corrosion on wiring, modules randomly frying. Then I have guys who use there whole engine bay harness shredded by mice and patched up and there cars operate flawlessly. Geuss living in a state where 6 months of the year is winter doesn't help. Ohhh bmw idk if I hate you more than I love you

It is called sadomasochism.
