Why does my Jeep Wrangler crank but not start?
Why does my Jeep Wrangler crank but not start?
Known good relays, no blown fuses. New ignition switch. Jumping ground to the control side of the starter motor relay will allow the vehicle to crank great, but won’t start, assuming due to no instructions from the PCM to supply fire/fuel. What else can I check before I spend $$$ on a new PCM + programming?

What should the battery reading be on a Jeep Wrangler?
Batteries use CCA (Cold Cranking Amps) to measure starting power. Be aware that your battery could have power, however, when under load, the cranking amps are not powerful enough to get the starter to crank the engine. A good fully charged battery should read over 12.6 volts. If the battery reads 12.45 volts or less, it is low.

That and make sure to step down on the clutch just in case because that clutch interlock switch is in the starter circuit. Or if it’s an automatic, try moving the shifter between Park and Neutral to see if that helps since the automatic’s park/neutral-safety switch is also in the starter circuit.
