Cherokee Hybrid Fuel System Issues, Expert Help Needed

I faced a similar situation with my 2019 Cherokee Hybrid last winter. I have some experience working on cars, but fuel system issues require proper automotive diagnosis equipment. The symptoms matched yours exactly, rough starts, engine stalling, poor car performance, and increased fuel consumption. After checking error codes, my workshop conducted a thorough fuel system pressure test to verify gasoline delivery problems. The root cause turned out to be a faulty wiring connection to the fuel pump. The repair involved: Complete system diagnostic scan, Fuel pressure testing, Locating and replacing damaged wiring, Clearing error codes, Test driving to confirm fix Total repair cost was 95 Euro and took about 2 hours. The car has run perfectly since then with normal fuel consumption restored. To better assist with your specific case, could you share: Current mileage on your Cherokee, Any recent maintenance or repairs, Specific error codes stored, Weather conditions when problems occur, Whether the issue happens with both cold and warm engine This information would help determine if your situation matches what I experienced with the wiring issue.

Thanks for sharing your experience. My Cherokee has 194017 KM on the odometer, and the last service was just a routine oil change 2 months ago. The auto repair shop pulled codes P0087 and P0171, which align with the fuel system pressure issues you mentioned. The pump failure symptoms occur consistently regardless of weather or engine temperature. After reading about your wiring fix, I checked the connections, but they seem intact. My guess is the pump itself needs replacement based on the consistent pressure-related codes and symptoms affecting gasoline delivery. Would be great to hear if others have dealt with actual pump replacement rather than wiring issues in these models. The car performance issues are becoming more frequent, so Im looking to get this resolved soon.

Thanks for the additional details. Those codes and symptoms at your mileage point more toward a failing fuel pump rather than the wiring issue I experienced. After my wiring fix, I actually did end up replacing the fuel pump about 6 months later when similar symptoms returned. The fuel pump replacement involved: Draining the fuel tank, Removing the fuel tank for pump access, Installing new fuel pump assembly, Replacing the fuel filter as preventive maintenance, Verifying proper fuel pressure, Clearing stored error codes Total repair cost was 650 Euro including parts and labor. The job took around 4-5 hours. Since the replacement, fuel consumption returned to normal and all engine stalling issues disappeared. Some tips from my experience: Get a complete fuel system pressure test before replacement, Consider replacing the fuel filter at the same time, Use only OEM or high-quality aftermarket fuel pump parts, Have the fuel injectors checked while the system is open Given your mileage and consistent symptoms, a fuel pump replacement is likely the proper fix. The P0087 code specifically indicates fuel rail pressure too low, which is a classic sign of pump failure.

My Cherokee has been in the shop for two days now. After reviewing all the responses and comparing symptoms, I decided to proceed with the complete fuel pump replacement. The car mechanics confirmed low fuel pressure readings matching the P0087 code, indicating definite fuel pump issues affecting gasoline delivery. The quoted repair cost is 680 Euro, which seems in line with others experiences. They recommended replacing both the pump and filter to ensure optimal car performance. The workshop estimates 4-5 hours for the complete job. The symptoms match perfectly with what others described, especially the consistent pressure issues regardless of conditions. Ill update once the repair is complete, but Im confident this will resolve the fuel system problems. Thanks everyone for the detailed responses and repair insights. This helped confirm my suspicion about the pump being the core issue rather than just wiring or sensor problems.
