2009 X5 3.0 N52. Car takes anywhere from 5-25 cranks to get started on cold days. Typically 40’s or below. Runs fine once started and all other times. New fuel pump, injectors, plugs, coils, and starter. Battery was replaced with a Duracell agm battery with 50 less cca, could this be the culprit?

Fuel pressure is good and doesn’t drop after shut off. Alternator charging at 14+. Coolant temp reading is correct.

Any ideas?
