Uh, the SXT is not an SRT or a Hellcat, so there's that. Then it might be a fuel pump or the fuel pump relay.

 

Battery…always the battery

Not true. Had mine replaced and it’s still doing the same thing as theirs.

 

You'll get a ton more responses in the third generation forums.

 

Yes, you plebs shall not tread on this forum!!! This is for the privileged only!!!! Harumph!!!🤣

 

Sound like the fuel pump is not holding pressure in the line. My 14 did this for a while, it was mainly after it sat for a few hours. I started turning it on without pushing the brake so the fuel pump would build pressure, then it would start on the first try. After a while, it went back to normal and hasn’t done it since. Self healing I guess. Actually, it could be that when I swapped the motor, I started using premium fuel. The higher grade fuel may have more detergents and other things that help keep the system cleaned out. I don’t know!

 

Thank you! This makes a lot of sense, since I always push the start button with the foot on the brake without going thru this intermediate stage “ACC”, where it is supposed all the accesories are getting ready.

 

My 2018 Chrysler 300 with the 3.6 started doing this about a month ago. I have been doing what Tony mentioned by letting the fuel pump prime before the first start of the day. Doesn't do it after that, just does it after sitting a while. My searches online have pointed to the fuel pump being the issue although some people have mentioned that after a while theirs finally threw a code for bank one cam sensor.

 

I have a 2018 Durango SXT Plus with 40k miles. It was running great until a couple of weeks ago. The first time the issue showed up was when I pushed the start button and took longer than usual to fire up. After that, the issue started to show up intermittently taking longer every time to fire up, but always started. Yesterday it didnt start, so I pushed the button to turn it off after 6 to 8 seconds the starting engine was turning. When it stopped I pushed it back again and the engine fired up just fine, like nothing happened. Today hapenned again (didnt fire up at the first try) just one time from the 3 I used the car, so my concerns are: first it seems to be randomly, second: I dont have any message or check engine light on, and third: this looks like it is getting worse until eventually it wont start again. Talking to a friend we thought it could be the fuel pressure regulator, since this device is mechanical and no electrical (otherwise I would be getting the error code) the battery is ok and the air filter too. Any thoughts or similar expereriences?

Did you ever figure this out? My 2015 is doing the exact same thing.

 

Friend has a 2016 doing the exact same thing

 

I had my battery replaced because the dealership said it was that. I didn’t believe them but had it replaced anyways. It was not the problem. Has your friend found the problem? I’ve taken mine to now 3 different shops hoping someone can find the problem. No luck. Fortunately for now it does always crank up eventually. I’m just afraid one day it’s not.

 

She had a new battery, replaced fuel pumps relay switch, spark plugs, sensors will run great for a few days then when she stopped to get gas turned off would not start back up. Usually sets for 24 hours and starts but tried this morning and would not start. Still owes on it can’t get rid of it

 

Dang. so frustrating! Spending all that money to have it fixed and still have the same problem.

 

I have the same issue. We have found a temporary fix by changing the fuse. It works for a few weeks and then stops. First time we swapped it with the horn fuse. I have explained this to two different dealers and they both have come up with other “solutions “. I have replaced the battery, fuel pump and even key fobs. Fuses are the only fix we can find. My 2015 Durango Limited has only 62000 miles.

 

It's not the fuse but the removal of the fuse. A logic circuit may need that power so when you swap the fuse, it loses power and resets or your TIPM is the problem but each time you exercise the fuse socket, it makes the connection better for a bit.

 

A intake leak will produce this symptom

Fuel pressure is a great place to start tho

 

Mine does this too..but won't do it at dealership

 

I’m also experiencing this and I’m here to see what’s wrong

 

I had this problem and brought it to the dealer 4 times. Each time they replaced a different part. I finally brought it to our local mechanic and he replaced the fuse box. Issue solved

 

Tiara, tell us the year, model and mileage of your Durango. Information is king.

 

How do you prime the line?

 

Have you considered the starter?

My 2014 was acting like what you described. I replaced the starter and boom it started everytime on the first couple of cranks again.

 

You prime the fuel pump to see if it's weak by pressing START for a few seconds without pressing the brake. Then start it as normal. If it starts right up then it's the fuel pump or the fuel system.

 

What fuse did you change?
