My 96 XJ starts quickly when cold and sitting all night. If I've been driving and turn it off for an hour or so, it really cranks to start. I mean like 5-6 seconds easily. Cold....maybe 1-2 seconds max. It has new cap and rotor from previous owner right before the sale, but not sure if he changed plugs. I'm thinking I need to pull a plug and see what they look like....may just need gapped right also.
