Well I need you to check on and do a couple of things to provide you better assistance.
First, please go to Auto Zone or O'Reilly's and for free they can pull the codes to the car. Most important. Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for free also they can bring their tester out and check your battery, alternator and starter.
If I understand you correctly, when you say it will turn over normal but does not even try to start, you turn the key, the engine is spinning, making the normal sounds of a starting engine it just doesn't fire off. Right?
We need to figure out if it is electrical or fuel related. Next time it does this pull a plug wire and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don't have your hands on any part of the metal!
If there is no spark, then it is electrical. If you are getting good spark then you need to get a fuel pressure check on the fuel pump to ensure it is putting out okay.
You have some good miles on the vehicle. It must be a good one. So it is definitely time for things to need replacing.
When was the last time you did a tune up. Plugs, wires, fuel filter, air filter.
Also, you may have numerous recalls on various items on your vehicle. I believe the dealer will pay to have these fixed. I have attached them for you. Please contact the dealer, provide the service department with your VIN and have them see if any apply to you.
Then do all the above and get back with me and we can take it from there.
