Durango not starting

I have a 2012 Durango. Periodically it will not start. Either it will start and then stop immediately or not start at all. It shows no codes, no check engine light, nothing. Took it to dealer and of course they couldn’t duplicate the issue so they suggested changing the plugs and wires. $700 later and get it Home go to start it up and same issue....started but didn’t make it to idle before it died....could it be the fuel relay? Ideas?

    You can't get to the bottom of this problem unless you have diagnostic equipment at the ready when the no start occurs. First thing you'd have to determine is what you have "lost"--either spark has checked out, or fuel supply, or injector pulse (to open the injectors).

    To diagnose those items, you will need a spark tester, a fuel pressure gauge, and a NOID light (for the injectors). The dealer was just throwing parts at it and taking a guess--not a good method of diagnosis. Spark plugs and cables don't suddenly go to sleep and then wake up again.

    My best guess is that you have a module or sensor that is failing sporadically, or bad wiring. So it could be a crank sensor, cam sensor, ignition coil, fuel pump relay---things like that. These items are sensitive to vibration, cold or heat, and corrosion.

    Another thing to check is your fuse box, to see if anything nasty is going on in there--green crud, loose wires, etc.
