2005 14L Series 60 - TomHanson - 11-18-2024
Engine runs rough. In the past 4 months, I've replaced #1 and #3 injectors two separate times. This would instantly fix the rough idle, and cure my "injector #1 response time long" fault code. Now, the same issue is happening. Went through all ecm data to find fuel temp and ambient air temp show -40 degrees f, which were the only odd things I could see. Truck came in this time with a plethora of inactive faults, and 3 active for injector 1 - response time long, fuel temp sensor - input voltage low, and oil pressure high. I'm leaning towards something in the harness at this point, I was curious is someone could get me some troubleshooting trees for these to at least point me somewhere? Or give me some input on some things to check...

First thing. Individually load test each battery. Inspect and clean all battery and starter connectors. Inspect cable to starter and alternator for rubbing.
