  1. JT 3.0 Diesel with ongoing P2635 Error

    Need to ask you...do you park on an uphill grade? I have detected this code, and cel on my 2022 ecodiesel gladiator quite a few times and it is nearly always due to a grade, parked overnight. When I park on an uphill grade, I do several non start priming cycles to pressurize the low pressure...
  2. Coolant Loss Explained?

    Thanks for info, pictures and thorough description. Very helpful.
  3. Anyone storing traction boards on back bed wall?

    This may not help, but since the traction boards are an item I need handy in snow, I stow mine above the back seat, wedged against the ceiling interior side by side, using two short plastic paddles or bills if you prefer (bolted on to Amazon cheap traction boards) and two short pieces of...
  4. Fuel line recall (inspection)

    If anyone knows that there is, a "new" pump, and what it is please tell us all. I am a doubter on that.
  5. "crazy-town" "SAPS" topic. Diesel Oil Changes.

    Thanks so much...this kind of info helps a lot, availability is not always certain for any brand.
  6. Having same problem after fuel starvation was fixed! Anybody else?

    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...
  7. ELECTRICAL WARNING TO ECODIESEL OWNERS: Shifter Controller Wiring Harness (Service Shifter error message)

    Brandon...items like this are why I pour over this site regularly. I can figure out what tires I like and whether or not I want to make a gear change, but this info and alerts like it are so valuable. Thank You. I have had to make several corrections and always prefer to be proactive. Dealer...
  8. Jeep lost acceleration and said “shift to P then desired gear” while on the highway

    All responses seem to be reasonable trouble shooting this...but I will pass on one of my experiences...did you by chance have a coffee cup in the holder closest to the shifter? I did and the finger ring on the cup facing forward contacted the shifter...bumped it and I was thrown into that mode...
  9. HPFP aftermarket fix?

    Depends on mechanical level of experience. The recall procedure instructions walk through replacing fuel lines to left and right side injector banks, and last fuel line which is a pump feed. The pump itself is a rebuilt, precision machined CP4.2 with the filtered (damage control) fuel return...
  10. HPFP aftermarket fix?

    I am running this pump now. Did it myself in November, followed Stellantis (Jeep) recall procedure instructions. 5000 miles since swap, no issues with the pump, and from my research, all of the claims in the add (River City Diesel CPX) are valid. I will fess up if it ever fails. There is no...
  11. Ecodiesel Recall 01A HPFP Parts are Available

    I have a printed copy of the TSB 63 pages long with the two tree decision approach for running not running fuel pump only or full fuel system replacement. I did my own and am still waiting to hear if Fiat Chrysler motors/Stellantis will honor their promise to compensate for the parts and or...
  12. Ecodiesel Recall 01A HPFP Parts are Available

    Yeah...calm down. The proof of the pump being modified or not to improve reliability may never be known...even with the lawsuits against Bosch, the many years of recalls with Ford Powerstrokes with the Bosch CP 4.2 and Dodge Ram 6.7 Cummins 2018 t0 2020, and Duramax and Dodge Ram1500...
  13. Ecodiesel Recall 01A HPFP Parts are Available

    I believe you are wrong. Different part numbers and stamps do not mean different or improved construction of part. The recall procedure bulletin from Stellantis does identify the pump as REBRANDED with a recall part number. It does not appear to me to be a new part., just complying with a...
  14. Ecodiesel Recall 01A HPFP Parts are Available

    Guys...WHAT new pump? Nothing I have read or found or answers given by dealers and the Chrysler Fiat/Stellantis reps on the Recali(s) service line convinces me that there IS a new or different fuel pump. Just replacing them...and replacing them...and sometimes replacing them again. Anybody...
