Is there any way to check a coil pack on a 4.0? My issue is my jeep won't start, it ran fine now just won't start. I've checked fuel and that is good, how do I check for spark?any help would be great!!!!!

Check for stored codes first. Key: on off on off on look at odometer.

QUOTE=billzcat1;wsar10 is right on point on this oil thread - as usual. Anyone reading this would be well-served taking his advice.

Take a spare spark plug and plug it in to a wire and lay it on metal and watch for spark.
