Wait to start/water separator lights = stall while driving

Ive been having a major issue as of late, every time it has rained (everyday lately) the truck will stutter or completely stall out. When this happens the wait to start light and water in fuel light both kick on. Usually it clears up on hot days or when it runs for a while. Any clue on where to start to look for the solution?

Might want to start with draining your HFCM, replace the fuel filters and while you have the back cover off of the HFCM clean it out. Also, make sure you are running something like Diesel Kleen it will help disperse water and keep any growth from happening. Hope this helps

Ahhh ha!! I had the EXACT same issue with my 04 a few years back. It was a pain in the arse figuring it out because nobody had seemed to have the same problem before and wasn't positive as to what it could be. It took me a couple months to figure out. I tried just about everything, checked FICM, HFCM, PCM, GPCM, batteries, wire chaffing under steering column, etc. Finally a really good tech here suggested that I start looking at the wiring harness from the PCM to the FICM and the harness from the FICM to the injectors. I found both harnesses from a guy here that did a Cummins swap and didn't need his anymore, swapped out the harnesses and the problem went away. I have never had that issue again to this day.

Hope that helps you some.

yep definitely a short somewhere. what year is the truck? ICP sensors can short out and mess with anything VREF related.

if you still have a fuel heater you may want to try unplugging it, they are known to short out also.

You know even better than I do that there are MANY places that could chafe and short. That's why it was suggested that I not waste my time trying to find a wire that is shorting out in the whole mess of wire in the harnesses. I really couldn't tell you if it was the harness from the PCM to the FICM or the one from the FICM to the injectors that fixed my problem.

My truck is an '04. I haven't ever messed with the fuel system at all, I thought the dealership would drain the water/fuel separator during regular service :/
How much did the harness's cost?

It was cheap because it was used and I just happened to stumble on it because the guy had no use for it. You would have to do some diggin around here or try to find one through google.

How difficult was it to replace? I won't lie, I don't usually work on the diesel lol. I replaced the entire interior, converted the headlights, swap and updated the back. But I've always had somebody work on the engine for me (engine is way too expensive for me to screw up) would it even be possible to repair the harness? Most threads I read they just replace the whole thing.

It's VERY easy to replace in my opinion. As far as fixing the harness, like I said earlier, you are better off just replacing it instead of bumbling through all the wires to TRY to find a bad one.

Well I got a set of harness's off an '05 and I'm attempting to swap right now, it's turning out to be a little more difficult than I thought, is there any step by step instruction alas out there? And am I gonna run into any problems with it being an '04 and the harness being an '05?
