Fuel problem......wiring issue. Fed up
Have an 03 6spd 170000 miles had it 2 years and it's been nothing but trouble. Sometimes it runs good. Other times it runs awful and wont start. Dies randomly once its warmed up. It's been in 4 or 5 shops including dodge and no one can figure it out. So far I've had a new cp3, new injectors, put a new fass pump on it. Fuel control actuator. I'm at the end of my rope with this thing. Any input would be appreciated.

Clean all of your battery connections. Tighten all of your grounds and ensure the are in good shape. There should be a thread at the top of the page saying, you may have a shorted wire. Read it and check the wire going from you compressor over the high side A/C line. They have been noted to chaff and through intermittent Cam sensor codes but not always. The truck will run like crap.
Do you have any gauges? Fuel pressure, Rail pressure? Fill out your signature so we can see what you have. It's in the user CP section.

This thread, they removed the sticky.

You may also have a bad PRV valve.
That's the rail pressure relief valve, if it stays open it will shut the truck off and return the fuel back to the fuel tank not allowing enough pressure to build up. They are expensive from Dodge. Get it from a Cummins dealer.
