I have had this jeep for almost three months when I got it I ran like **** I put new Coil and plugs and ran amazing though the winter snow It started draining the battery so I was disconnecting the battery every night then one day I drove it and it started like hiccuping and sputtering when I turn it off their is a after market Security system installed by someone who had no idea wtf they were doing Also the security was jimmy rigged going into the key halo fob area were the key go in Also, the security system has a wire going from the computer of the security system. All the way out to the first fuel injector I have put a new cam Positioning Sensor and crank shaft positioning sensor. I also replaced Spark plugs again and coil and still geting no spark

 

Punctuation is your friend. Use it. What is the actual problem you are having? Crank no start, or not cranking at all?

Aftermarket alarm systems can be tough. Knowing it was running good at one point is a good sign that its something small.

 

Sounds like that hacked-in security system is causing your issues especially with that janky fuel injector wire and no spark. Rip that crap out and rewire it properly. Check for blown fuses or fried wiring while you're at it. Could also be a bad ECU if the security system messed with it.
