Make sure battery has a full charge and connections all good. I looked at info for 4.0L engine. Did you check for trouble codes? Engine cranking, did you check primary voltage to coil pack? Use a test light to check for voltage. Top wire to coil in the picture, As you can see, it is fuse protected and voltage comes from asd relay. Some makes and models, the computer has to see both the crank and cam signals or it won't ground the asd relay. Don't replace anything unless your testing points in that direction.
