Engine Stalling; 2,300 miles from home!
First, i just want to say that this forum has been really great!
I recently did an injector cups job on my 7.3 about a week ago. I got the truck ready for a trip from yuma, az to livonia, mi to visit the family for christmas. While i did the injector cups, flushed the coolant system, differentials, transfer case and replaced the fuel filter.
When I made it to livonia michigan on the 22nd, the truck stalled while in a traffic jam. The issue has gotten worse in the past couple days and happens much more often while driving. It happens mostly when i'm trying to accelerate from a dead stop. It also happens when i let my foot off of the throttle and then reapply throttle, so in all cases, the engine is at idle and i'm trying to give it throttle. A few times, it felt like i was not getting fuel while i was trying to accelerate and then it just died. I read some threads and a majority of the threads pointed to the cam position sensor (CPS). I replaced that today and the issue is still present. I drained the fuel bowl and I checked my recently installed fuel filter and it is still clean as can be. I am not throwing any codes and the truck starts right up every time after it stalls. Voltage and oil pressure gages look good when the issues occurs, when it stalls, the battery light turns on. I checked the valve cover harnesses and those are connected and do not appear to be loose. The truck was around a 1/4 tank when i got to livonia, to rule out a cracked fuel pick up line in the tank, I also filled up the tank today and it is still happening.
