03 dodge hard to start and surging
We are working on a 03 dodge commonrail. Its hard to start sometimes, and when you get it started, the engine surges up and down. All injectors were replaced 2 months ago. One of the batteries had low voltage so we replaced it. We have another engine here, so we swapped the injection pump and regulator, with no results. 2 weeks ago a new transfer pump was installed. There is a skim key to pcm code in the computer, but it has been there for a year or so. ICP pressure is around 6000 at idle and 18000 at wot. Im having trouble figuring this truck out. Help me.

There is a group of wires up by the A/C compressor that gets rubbed bare. Spray a bunch of brake parts cleaner around there, then look for chaffed/bare spots. If it seems to run better afterwards, found the problem.
