3.5 L. egr valve location.

I would get it scanned for codes. With a scanner that scans all the modules. I wouldn't rely on the dash warning lights alone. Better to eliminate all possibilities. The 3.5 has a EGR valve. Remove it and clean out all the exhaust passages on it.

Restore the stock Dodge components. See what codes you have.

Did you find any codes on the stock system?

You need to have it scanned with a higher level scanner. One that can communicate with all the modules. The module that runs the display screen is called the TGW - Telematics Gateway module. It has a list of codes for it. Do this and post the codes. Then, I can check my resources.

This diagram as well.

2016 DJ P0172 Fuel system 1/1 rich information.

Here is a picture of the "one time use bolts" . This one is inside.

On my 2016 DJ, I wanted to paint the rails. Remove the end caps, you have 2 bolts that stick up through the roof. All these bolts are basically one time use factory bolts. They don't have full threads machined on the bolt itself. I loosened one nut up an could see it wouldn't tighten properly. If I removed the nut completely. I hand brush painted the rails. Left the other bolts and nuts alone. The one nut, that I did loosen did not fully tighten. Just snug. So to remove all 4 nuts. Would not work. They are not going to hold the rails tight to the roof.

Read my thread on the battery. https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/

If you haven't run the engine with out the serpentine belt on the engine. Since your repairs. I would run the engine until the noise is occuring. With the belt on. Remove the belt and run it a few minutes. Under the same load. To eliminate any possibility of the AC clutch or water pump pulley. Being your problem.

I would check everything that is run by the serpentine belt. Check all your engine fluid levels. Need a second opinion on this thought: Could you run the engine for a few minutes without the serpentine belt on it? To see if you hear the noise then. Only when the engine is cold, you do not want to overheat the engine.

There is TB relearn procedure required after you replace it. It's a function on higher level, bi-directional scan tools.

First thing to check with a battery drain. (parasitic draw). Remove the fuse marked HFM. Located in the Interior fuse panel located up and underneath the glove box. Also check for the glove box light staying on. Unplug it.

What year Journey? What engine?

For cheap and easy: I would replace the battery sensor. Check and clean all battery cable connections and grounds. Read these threads on doing that. https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/ https://www.dodgejourneyforum.com/topic/18374-electrical-system-fyi-ground-system/

I would like to know if the engine cranks over? Be specific as to the speed and how it sounds. Is it possible to post a recording of it cranking?

This shows the interior fuse box. https://www.startmycar.com/us/dodge/journey/info/fusebox/2011 Fuse #131. HFM

Find a pull the HFM fuse. Interior fuse box by glove box. Check that your glove box light isn't staying on as well.

2016 DJ power inverter information.

To replace the starter on a 3.6L. Everything you remove comes out from the top. The only thing you disconnect under the car is the catalytic converter flange bolts. Remove the front catalytic converter. Remove the motor mount bracket bolted the the engine. Located in front of the starter. The 2016 DJ service CD. Doesn't mention you have to support the engine before removing the motor mount bracket. You might have to remove the air filter box and air intake that goes up over the radiator. In this picture, I marked the starter cable, catalytic converter and the motor mount bracket.
