If the computer got wet, and you have been trying to start the engine, there's a good chance it is toast.
You would need to know if you are getting spark to the plugs, fuel to the injectors, power and a ground pulse to the injectors, and normal compression to proceed.
One of those things is missing from the equation.
Does the check engine light come on when you turn the key on ?

Did this happen overnight or was it a gradual loss? Did you do any kind
of repair before you lost the gas mialage? Is there a check engine
light on or did it come on and go off? Did anything weird happen before
the jeep got bad gas mileage? It's hard to diagnose a problem like this
without actually touching the car.
Any other info might help me steer you in the right direction.

when was the last time you put in fuel injector cleaner? I put in Lucas Oil Injector cleaner every other or every oil change.
There are alot of factors affecting your gas mileage. Tire wear, tire pressure, wheel alignment, air filter, fuel filter, spark plugs, oxygen sensors, just to name a few. So to say what you need is just shooting in the dark without more information. I would probably start with your oxygen sensors, and then perform a tuneup. If your vehicle pulls to one side or the other when driving on the highway you need to stop into the shop for a wheel alignment.

You might also want to vary where you buy your gas. I lost approx. 5 - 6 miles per gallon (translates to over 100 miles less per tank) earlier this year. After conducting a bit of an experiment I realized it was only when I bought gas from one particular distributor (Spinx). I have since stopped filling up at all Spinx stations and my mileage has returned to it's previous level.

Of course you are. Try drying it up and restart. If it still doesn't start, take the air filter assembly sitting on thecarburetor . Open the carburetor. Inside it, is a float, that closes the fuel valve when the reservoir is full and open it, when the fuel goes down the level. This control the fuel flow into your engine. You can adjust this such that it is just parallel to the cover holding it. Be careful in removing the carburetor cover. This hold a small valve just above the float. Do not lost it. When everything is checked up. You can assemble the carburetor, and screw it back in place.
Put the air filter assembly back in place. Now, that
you are done, you can restart your car engine. Good
working, you can do it.

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.
