Hi. You a dodge tech? HAve you checked the fuel control actuator on the hpp. If you disconnect it and see if it will run and the fuel rail pressure should full field too(25kpsi), on the scanner. It sounds like you may have a bad one. Idles poorly, stalls, but can try to keep it running with fuel peddle, then cut off. Sound close?
No, independent shop. Like I mentioned the truck runs with the fuel press maxed out. (Actuator disconnected) Yes It will run with partial pedal. I guess I'll order an actuator. Is there anything special about changing it?
Nothing special about changing it, just three screws and connector. What you have described sounds like the one I just had in here, and seems to be what most of them do when they go bad. I hope I was helpful. If you need anything else let me know.
