Default 2010 Jeep Wrangler cranks but wonít start.

For the past couple months my 2010 Jeep Wrangler wonít start, it would crank on and off when ever I turn the key, itís not the battery Iíve tested it and even bought a new one. Does anyone know what this could be or any ideas on how to fix it?

An engine needs 3 things to work (as least used to), i would start by making shur you are getting spark (check the plugs), next would be fuel. can typically do both at the same time as you crank it will spray and you can smell it on the plugs. it is very rare that you arnt getting air but ya. if the motor is getting all those then its something with the computer telling it not to run. and good luck on that part i know this sounds stupid and simple but it is the easyest way i have learned to lean me towards what i need to focus on more.

That's where I always start with a no start condition....well actually, I'll plug in my BlueDriver OBDII scanner 1st to see if there's any codes to point in the right direction of those 3 items. Spark+Fuel+Air=FIRE! and that's what an engine needs to run if it's cranking.
