Ive had the car since 39k miles now have close to 100k.
(2011 non-pp) Cranks fine usually first thing in the AM but say i go to the store or work then have to go to the bank after ive shut my car off, It usually wont start on the first push takes anywhere from 2 to at most 4. Sounds like it wants to start but just gives probably a rotation and a half and all the electronics come on i have to turn the car off and repeat. Battery is brand new prob 3-4 months old.
Made appointment with dealership for Monday. Any ideas?

Do you have a ODB2 scan tool to see if there are any pending codes?

One of the fuel pumps or the FPDP... I know when I replaced my LPFP or my HPFP it took a couple tries to start it as it primed the system...

You can also monitor HPFP pressure which IIRC needs to be 200 psi or more to start.
