Having same problem after fuel starvation was fixed! Anybody else?

[Mamajojo6mom]

Bought new 2021 Jeep Gladiator Sept 2021. Long story short because it's like so many others, our truck sat at service for 349 days - getting it back Dec 30, 2023.
On initial driving after recall was fixed it smelled like exhaust was dumping in cab but soon realized this was odor of the too old DEF product. Ran just like new though....
Fast forward, 2 weeks ago, drove on 15 hour trip for vacation and exact same problems as with old fuel injector started 5 miles from vacation location. Gave troubles that full week and way home and continuing.
Problems are bad chugging on call for fuel in take off and up hills at cruise speeds (with and without cruise), at stop light when apply gas completely shuts off - after putting in park and pressing start button will start/due immediately. On 2nd try, starter will run continuously for a full cycle (seems forever when traffic is behind you but maybe 20 seconds or longer?). Nothing we can do to disengage the starter, it just has to run that cycle. Then the 3rd attempt it starts. Will chug when apply gas in this instance as well as the times when it doesn't die at the intersection.
I have appt at service today - anybody else having similar problem after the recalled part was replaced? Thanks! Jo

It sounds like fuel starved or air in fuel, as often occurs when fuel filter is changed (part of HPFP fuel pump recall too), and started without a thorough air purge procedure completed. If this is not the case, are you seeing any fuel leaks or drips under the vehicle that you can trace to the fuel filter area (under and behind the driver door area) or the fuel pump area (passenger side in the engine compartment front of engine right side) and or its several fuel pump and injector rail fuel supply lines? Last, my own experience, fuel filter was loose after replaced, AND sensor wire bundle on passenger side, near exhaust was removed for convenience and access during the HPFP fuel pump replacement, and a pin in the connector cluster bent, not making good contact and causing odd outage in heater, overheat conditions, and limp mode until corrected/ properly reconnected. Good luck, just trying to help.
