just happened today. but when the engine is warm, it starts up fine. you think it's the spark plugs? they have about 25k miles on them. if not what should i check?

Tomorrow morning before you start it cycle the key slowly from the off to on positions (not start). This will pump more gas to the throttle body. After about 3-4 cycles start the jeep. If it starts easier I would replace the fuel filter, & if the problem continues check the fuel rail pressure. Replace the pump if need be!

That's not the fix though! Replace your fuel filter, & it should start first try!
