MM:
Since you have replace the pump, your issue has to be lack of power to the pump when the issue appears.
The Gen 3 Durango has had its share of fuel circuit relay issues for sure. From what I understand, dropping the tank is a PIA! I would hold onto the old pump for a spare, as it is probably good.

FYI here is the wiring diagram for the 2017 3.6 fuel delivery system.

As for the pump itself, there was a TSB for poor pump performance but it concerns accel/WOT.

 

Thanks for the reply guys. Im having a power issue with the batterys. The AUX was dead af n not charging. Im off to the stealership for a remote battery terminal fuse block n possibly the sensor on starting battery negative terminal.

 

Don't forget to check the fuse 52. Although IIRC there is a fuse in the battery area as well.

2017 Durango GT won’t start!

I was sitting at a stop light, and my Durango cut off with absolutely no warning. I finally got it to crank and got it home. The next day it won’t crank at all. The cab lights and dash lights come on, but when I push my start button, it just clicks and won’t turn over. We tried to jump it off...

Battery issues

Hello friends For the last couple weeks i have been having starting issues with my 17 durango 3.6L sxt. I had to jump it couple of times. Yesterday i replaced the main battery but today it took longer to start. Here are few facts 1. Checked all lights and made sure they are off 2. Aux...

Fuse 52 was good. Debating spending $90 on the IBS ( battery sensor). Read somewhere that it could actually cause a crank n no start issue if bad.

 

Test it and ohm it out if you can get it out of the circuit to do so.

 

Well I replaced the small battery, 150amp fuse and the IBS. It ran good for a week but now I'm stuck with the same issue of crank n no start. The fuel pump is not priming the system or running once cranked.

 

currently have the same issue with a 2017 dodge durango i brought down the old fuel pump and istalled a new one from truegrade brand and worked perfectly, a week later came back same issue crank no start, i feel we may have a problem somewhere with wiring. Has anyone found a solution Dealership is no help at all.

 

So pre-2014 jeeps and durangos suffered from bad relays that were not serviceable as they were soldered on the TIPM PCB. Then there was a TSB for chargers/challenger up to 2016 where FCA changed the harness/connector to the fuel pump due to bad connection (power/ground contact would melt the fuel hat). I have not seen any TSBs for the 2017 durangos and the wiring is pretty straight forward. If the relay and fuse are good and there is a signal from the PCM the pump should run. Now if it has enough pressure...that is a different story.

 

I checked fuses and relays Also both batteries when crancking the engine i see it sending signal from relay to fuse Im now wondering if theres a problem with the pump from autozone Or if its something from the wiring you sent me

 

So there is a TSB for 2017 concerning the fuel pump!

 

Send help 😅
Honestly is my first time with this problems on the durangos
What do you recommend send it to dealership?

 

Do you get any fuel pressure? Unfortunately to check you would need something like this.

If it were me, I would verify that the relay is getting voltage from the PCM and that the fuel pump is getting voltage. If not, then it is electrical problem. If yes then it is the aftermarket pump. I do my own stunts, tell my own jokes and fix my own cars so "sending it to a dealership" is not in my vocabulary.

 

My guess is the pump is the issue. Repop pumps, like sensors and thermostats, aren't very good. Try priming it by pressing the start button with no brake for a few seconds. Then if it starts with the brake / Start button then it's the fuel pump not holding it's pressure.

 

Could also be the connector to the fuel pump. Just remembered this member's issue which was common on pre-2016 challenger/chargers/300s and hence the reason for the TSB (should be a recall as the car can die unexpectedly and it can cause a fire).

Did you ever find your culprit? Our new to us 2017 Durango behaves the same way with the occasional crank and no start Thought for sure it was the stupid TIPM as the earlier Durangos, rams etc. Still makes me think a sticky relay or something.
