I had the same problem for about 1.5yrs. It started out as cranking after turning over about 5-7 times the first time but if I shut it down and crank it up again, it would fire right up.
In the beginning I could let it sit (after shutting down) for about 30min and it would still crank right up. However over time, I couldn't shut it down and run in the store for 5 min without it having trouble cranking. I took it to a mechanic and as I've read in all the forums, he suggested it was the fuel pump. $550 later it was not the pump. He cleaned the injectors cause he said they were clogged and that didn't solve the issue. I finally just took the jeep since he didn't have a clue of what the issue was. I replaced the fuel filter, crank shaft position sensor, temp sensor, plugs, and nothing worked. Finally I read an article that mentioned leaky injectors. I did the poor man's test but didn't have a leak. I did however think it was an injector issue, maybe clogged or failed. So I purchased on injector from O'Reilly's for about $40, took the injectors out and noticed all were shiny except #6, it was a dull color. I replaced that this weekend and the jeep cranks every single time just like new.
I have seen so many articles with people having the same issue but the thread would die off with no solution noted. I hope this fix will be able to help you guys and hopefully save you some money and offer a solution that doesn't take 1.5 yrs to come by.
