2019 Dodge Charger Pursuit 5.7
During some startups, car will have trouble starting. Either it will immediately stall (1-2 cranks>stall), or it will be long cranks (cranking.......no start), or it will be a hesitation start (cranking..pause/almost stall>start). I've gathered that pressing/pumping the gas pedal helps start the car every time the issue happens. Priming before crank changes nothing. No specific pattern / does and does not occur on cold/warm/hot starts. Might happen 3 times in a row, might start good 3 times in a row, and so on.
I tested (few months ago) fuel pressure(old pump), don't remember exact numbers but ~53psi cranking, ~58psi idle, dropped ~2psi after 10mins shutoff. I just replaced the entire pump a few days ago in the event it was still pump related and issue is still present.
I've replaced CKP sensor, spark plugs, (driver) fuel pump, IAT sensor, upstream O2 sensors, cleaned throttle body, tested fuel pump relay, maybe other things I'm forgetting. Only code I have is P0456.
Any help is greatly appreciated🙃
