No Bus on dash

New better starter? What is a new "better" starter? As long as it's a factory replacement starter, there shouldn't be any issues with it.
 
I finally got it started after flipping key on and off a million times and replaced switch to get it to “wake up”
 
I see no reason the alternator wouldn't cause this issue. A lot of people put the higher output Durango alternator in without issue.
 
Update when the engine gets warmed up the no bus doesn’t show up? Could the connections be shrinking because of cold weather?
 
I doubt it. But it wouldn't hurt to pull all the connectors and put dielectric grease in all of them to make sure the connections are solid.
 
See when it’s at operating temperatures it doesn’t occur but I have to flip the key on and off like twice for gauges to work

It might be time to start looking at the PCM as the culprit. When the PCMs start to go bad, things can start acting wonky.

The first thing to do is reset the PCM by unplugging the battery for 10-minutes or so, then re-connecting it. But if that doesn't work, I believe there are methods detailed in the FSM on how to test the PCM.

In addition, there are companies you can send yours out to who will test it for you (and even rebuild if necessary).
 
Sweet. Will do this weekend but can’t seem to find the pcm section in that fsm

I haven't looked at it in a long time. I'm not sure if they refer to it as the PCM, ECU, or possibly just "computer".

Open it up on your computer and do a "CTRL+F" on a PC (or CMD+F on a Mac) and you can search for those keywords. That's how I always make finding things easier in the FSM as oppose to scrolling through countless pages.
 
Okay it’s reading .7 guess I figured it out. I took a wire connected from battery to the or/dB wire and no bus went away so I think I’ve discovered it
