HELP!

pistolp0440 · 07-20-2023, 12:07 PM

This is my first time on here and I am at a loss. I have a 2005 545i. While back car would crank but not start. I checked spark (spark plugs, coils, wiring) and replaced fuses and the relay. I have spark. Still had the issue and sprayed starter fluid in the intake and it would crank and start. So, after hours of youtube I replaced the fuel pump and fuel filter. Still has the issue. Sometimes it will start and sometimes it will not.

Codes it throws are: (1) P112B "DTC definition not found" and (2) P0017 "Engine Coolant Temp Sensor" - which I replaced last year.

Any ideas would be a HUGE help. Thank you!
