Need help long crank.
Hey guys I have been tackling these shadow codes for a long time now on my 535i and I just don't know anymore. The codes are as follows:
11A401 - Fuel high pressure during fuel injection release: Pressure too low. 11B401 - Fuel high pressure or after enabling injection (2nd ambient condition set after delay): Pressure too low. The only symptom I get is a long crank and I would lose fuel pressure slowly while the car is off. I still get full boost (MHD stage 1). A lot of people told me it wasn't my hpfp due to it still running good after start. So I replaced the low pressure fuel pump and bam no codes and no long crank. A few weeks later i got the same codes again and long cranks again. I don't know what is is anymore. I don't know if the new pump was faulty but my car ran great for a few weeks and got the same exact issues from before!! |
