N54 Cranks but won't start
Hey, what's up guys so I'm having an issue with my 07 335i. It all started one morning when I went to go start my car and it sounded like absolute dog shit so I shut it down and hookup up a code reader and I got codes for the crank sensor. So I went ahead and installed a new one and it would start but then shut off a few seconds later. After that, I jumped down the rabbit hole and started replacing everything I could think of based on the codes I was receiving from the DME like the HPFP, LPFP, Vanos solenoids, and the cam sensor and still, nothing worked. Now after a few months of thinking I figured id just try starting over and replacing the crank sensor again just in case I got a bad one and BOOM no more DME codes. Now, whenever I go to start it all it does is crank and won't turn over. I plugged in my code reader and all I get is a CAS code: A0B4 engine start starter operation.
If anyone has any idea what may be going on I would gladly take any advice you may have. Thanks
