1999 Jeep Cherokee mileage: 100,000. My Jeep will crank over, but it will not start, it doesn't have spark. I added new distributor cap and rotor, still no spark. Checked coil with an ohmmeter and seems ok (0.6 ohm between + and -. 6,500 ohms between + and anode. Infinity to core), suspected the ignition module, but it tested okay at the parts store. Ignition Module was replaced two years ago. The engine crankshaft sensor was replaced three years ago. New plugs and plug wires one year ago. What do you think?
