Well you need to do give more information :
1. Fuel are you getting fuel ? Do you have to pump the gas on the 3rd attempt ? Do you have fuel injection ?

2. Is your starter cranking on the 1st attempt if not is your battery charged

3. Ignition is it old school coil ICM distributor ?

4. How does it run when started ? Any stalling ?

I need more information about you Jeep to help you .

Ok it sounds like a fuel problem . I would start simple and clean the injectors and see if its a lack of fuel flow . Also check the fuel filter I always start with the simple stuff .

fuel pressure regulator is notorious for causing this problem
