Turn ignition key; no engine turnover. No warnings or previous issues with starting. No previous problems with 3-month old battery, which is fully charged/charging. Turn key and, under dash, near firewall, hear a "popping" sound. Not chirping. Help!

no engine turnover. If you meant it cranks over and will not start do below to determine if its fuel or spark issue

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Hey, Rasmataz. Thanks for answering my poorly worded question. The Wrangler does NOT crank...at all!

Load test the battery if okay clean battery posts/cables and tightened properly don't work start checking the starter, starter relay, clutch switch and ignition switch
