It may be that it is not getting a hot enough spark. Check the CCA (cold cranking amps) rating on your battery. If it's 650 or below, that may be your issue, a cold battery has less power. Try upgrading to a battery with more CCA like 750 CCA or above. Or if your vehicle is garage or carport kept, simply buy an extension cord and a heating blanket, really! Just open your hood and drape it over the "cold" engine at night...Worked for me with my old Datsun 280Z.
the easiest way is to remove the whole ignition swith which requires security star bits the ones with the holes u can get them at some auto part stores or harbor freight. once out find the movable pin put the key in and turn the key till the pin will push in and the tumbler shoud slide right out, its been a while so i cant remember the position just play with it
The fuse it doing it's job, you have a short ( Wire that is connected to a ground, that draws too much power )
If you have an electrical schematic ( Repair manual ) find out which wires are connected to that fuse and check them for any chaffing, cuts, unnesassary twists, or corrosion.
If you have a ohm-meter, isolate the system ( by disconnecting the fuse, and other connections. Then check for any resistance on wires that should not be connected ( because you disconnected them ) by having one Lead on the wire's connector and the other meter-lead on your car's frame. A good wire will not have continuity if it is isolated.
It seems strange that you have this starting/no power issues when it over 70 degrees outside but not when it is cold. When it is cold the battery and starter are normally under more pressure to start the engine and it is also harder to burn and atomize fuel when it is cold. The reason I suggest removing the trim panel and checking voltage at the ignition switch is that is the best place to start. The ignition witch has to have power present at the switch and must distribute that power as the key is turned to operate accessories and the starter motor when turned to the start position.
Try resetting the asd "auto shut down fuse had a similar problem the jeep would crank but did not get spark or gas also check your fuel pump? and the asd relay may be bad it will prevent the jeep from getting no spark and will not fire some jeeps have security problems
