Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

Check the crankshaft position sensor, i have repaired 3 Jeeps (after the owner spent a lot of time and money replacing fuel pumps,TPS, and many other items) then got frustrated, brought it to me and within an hour it was running fine with a new CPS
Having same issue with my 2000 grand cherokee. sometimes fuel pump will prime and car starts the other 50% of time no fuel pump noise only smaller radiator fan will come on and make vibrating whining noise. I have changed out fuel pump and filter as well as checked and ruled out all fuses/relays involved. Need help too
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.
OK...I have a 93 outside...one diagram I have shows an ignition module next to coil...but there is none on mine, (4.0 engine) Two items to check are crank sensor and cam sensor inside distributor. Test procedure can be found in just about any manual including haynes. You will need a decent volt/ohm meter to do testing. You can also check codes by turning ignition switch on/off three times, leaving it on the third time. Check engine will flash code #'s (ex: one flash, pause two flashes= the number twelve.then followed by a longer pause then another set of flashes etc.)
