    I drove to work this morning and my Jeep ran fine. I had to go and drop some paper work off and when I went out to start it the engine was turning over but wouldn't start. I'm wondering if anyone else has experienced this on a 2012. I'm thinking if could be a fuel pump or filter issue.

    Welcome! Subbed, as I have heard about this, but not sure what the issue could be.

    Of course, it can be a fuel pump or filter issue. There are plenty of things it can be. While there are others, you can make an assumption it is missing either SPARK or FUEL. However, there are multiple possible reasons for each.

    Do you smell gas after it has been cranked for a bit? (is it flooding?)
    If NO...then fuel is a likely assumption. If yes, then spark/electrical is a better guess.

    You should be able to hear your fuel pump prime itself when you turn the key on (not to the "crank" position). Do you hear it? If so, fuel pump is likely working though that still does not eliminate fuel from being the issue.

    Of course, you should DOUBLE CHECK the simplest thing... are your battery terminals TIGHT? Don't laugh...it happens and yes, even when it cranks because of grounding issues.

    When all is said and done, I suggest taking it to a dealer. This can also happen due to the TIPM, crank position sensor, and the Throttle Position Sensor. TIPM issues would seem to be most common.

    Sorry to be so little help...
