Question edited for clarity. Cranking IS turning over. You are cranking but not firing, or starting, or running.
If you haven't much pressure at the rail, your likely problem is not enough fuel pressure and the fuel pump needs replacing. One post here says you need 39 PSI and another says 49 PSI. What do you have? You need to test with a pressure gauge.

Carefully check your routing and make sure that all spark plug wires are attached to the correct spark plugs otherwise your firing order will be mixed up and cause the issue you are having. Also make sure that the wires are firmly seated on the coil packs or distributor, whichever is on your vehicle.
Check all the vacuum hoses on the intake manifold for a leak. Replace all broken and cracked lines. Check from the coil to spark plug wires with an inline spark tester for fire. Check the spark plugs for fouling and cracked terminals. Inspect the spark plug wires for worn or cracks. If you can check the fuel pressure to the throttle body. Also look at the air filter. Hope this will help you.
CHECK ASD RELAY THAT IS AUTOMATIC SHUTDOWN RELAY IN THE POWER DISTRIBUTION CENTER UNDER THE HOOD IN ENGINE COMPARTMENT.IF ASD RELAY GOOD PROBLEM COULD BE CAMSHAFT SENSOR IN THE DISTRIBUTOR.TO SAVE TIME AND MONEY HAVE JEEP SCANNED FOR CAMSHAFT SENSOR AND CRANKSHAFT SENSOR FAULTS.
The first thing I would do since you think it was flooded is to replace the sparkplugs, sometimes if a spark plug has been washed out with gas you cannot get it completely dried out. After you replace sparkplugs try to start the engine. If the engine starts I would still recommend that you change your oil because of fuel saturation. If your engine fails to start I would suspect that you have a bad crankshaft position sensor as it is known to give problems. The crankshaft position sensor is located on the top of the transmission bell housing on the drivers side.
First I would change the plugs, wires, distributor, and rotor button next I would make sure the firing order is correct then have timing checked if all check out have the cylinders tested.I hope this get your Jeep up and running. Please Rate Me . And you can always ask me
