I believe that year had distributorless ignition, instead it uses a form of coil on plug ignition system.

If you open the hood, stand at the front of the vehicle. Look to the left side of the engine, around the bottom of the valve cover (The valve cover is where the oil fill cap is. The oil fill cap is on top of the valve cover), at the bottom of the valve cover on the left side you will see a series of humps. Those series of humps is the coil packs, the coil packs are all in one long piece held down by three or four bolts.

Take out those bolts, gently pry up at the ends of the coil pack and it will eventually come out. You'll see on the bottom side the spark plug boots are attached to the coil pack. After you get the ignition coil pack off, you will see the spark plugs under where the coil pack came from, the boots on the coil pack sit directly on the spark plugs.

SOURCE: 1993 Jeep Cherokee 4.0 turns over no spark.

Most common cause of this is a bad crank position sensor. However, do not change it before testing. Test between the b and c terminals of the connector with a digital volt ohm meter (set to ohms) You should read an open circuit there (same reading as if both leads were not touching each other and the meter was turned on) Anything different means it has failed. If it checks out as good, then get yourself a chiltons or haynes manual and follow the test procedures outlined in them. Worst thing you can do is start buying parts and hoping it will solve the problem. If you do that, likely, you will have an engine with lots of new parts that still does not start.

Check the coil itself,or replace it.The e c m sends power to the coil,12 volts,but it also breaks the ground side of the coil to load it,to fire on time.
