Why won't my car start?

Sorry. Didn't complete the information field! Car turns on and tries to start but won't. This happens sporadically. I can go weeks and it won't happen. I tried jumping battery...wouldn't start. I tried pumping gas peddle...wouldn't work. Sometimes these two things work: I get out of car. Hit lock button a time or two...starts right up or I will turn car on but not try to start it and wait a few seconds to a few minutes and then turn it off and back on with start...starts right up. Dealership said no code was showing and they don't know because it didn't do it for them. Had someone clean out the CO2 throttle system (??). Didn't happen again for two weeks. Had another shop look at it. They think maybe the alarm system (my computer system thinks my car is stolen?) or maybe the chip in the key is not being recognized at times. I have a 2012 Durango with about 74k miles on it.

You might want to try manually starting it with the key inside the FOB. Use a smaller key to pop the start/stop button off and inside should be a keyhole. Pop the key out of the FOB and start it how you normally would with an older car. That happened to our Durango, and it started fine when we did that.

I have 2013 Durango does exactly same. Fob key worked for while but still happens but get worse. There is a recall from Didge for this. It is either the fuel pump relay or fuel pump. Should be replaced by dealer.

***DONT TRY ANY EXPENSIVE REPAIRS until you’ve tried this...MUST READ*** I have a 2013 Dodge Durango RT w/ 69k miles with same problem. My vehicle had the recall remedy performed at some point before I bought it where the dealership installed an external fuel pump relay (Omron G8JN-1C6T- F-R-DC12 2635A11 is on the remedy part they installed). I was really dreading a fuel pump replacement thinking there was no way the part the dealership installed as part of the recall remedy would fail. I tried a fuel additive thinking maybe there was sediment or something in line. I also tried the ignition resetting steps as stated in other forums/threads without much success. As a last ditch effort in an attempt to avoid facing the reality of a fuel pump replacement, I pulled out the fuel pump relay from my 2005 Dodge Magnum RT as I figured since both were 5.7L Hemis it was worth a shot. Even though the part #s were different, the Durango started right up. I wanted to make sure it wasn’t a fluke so I removed the Magnum one from the Durango, re-installed the recall remedy replacement one, & the Durango wouldn’t start. I then re-installed the Magnum one into the Durango & it started right up again. This proved the recall rememdy replacement was defective. After going round & round with the dealership that the recall remedy replacement part failed & that the part/repair/tow should be performed for free they told me they were out of stock & it would be atleast 3days before they could even get the part in & then I could schedule an appt for the repair but no guarantee of same day service. My family could not go a minimum of 3days without the Durango so I asked if they had the one from the Magnum instock. They did & instead of dealing with the service/parts dept anylonger & having to catch rides back/forth I just went home & did the repair myself. It’s been about a month now & the Durango is starting right up every time without any issues with the part that is for the Magnum. So if your dealership doesn’t have the Durango one, see if they have the Magnum one. The info from the Magnums part bag reads: “0472 7370 AA - 002” I hope this info helps someone with the issues many of us are having weather we’ve had the recall remedy performed or not.

It started the check engine light came on and it was blinking and it was vibrating and I took it to the AutoZone and I change the spark plugs and it will it will crank but it won't start

My 2013 Dodge Durango has had recall replacement of fuel relay. Now I replaced both fuel pumps. Worked a month and doing same thing. Going to try the key trick and then use the magnum relay switch. So frustrating!!!

It IS the damn relay which is 17 bucks at Auto Zone. I’m happy and livid at the same time.

Anyone have luck with the relay being replaced? I just had the dealer replace both fuel pumps and it worked 1 week and now won't start.
