2000 Jeep Wrangler

Ok first some info needed. You have no fuel filter that is replacable on your jeep as it part of the pump so, how is the fuel pressure when it is cold. Get a fuel pressure tester and connect it to the fuel rail (before starting it) note any fuel pressure. Turn on the key note the pressure change. If you do not have a fuel pressure tester or access to on then do this instead. Turn on the key you should hear the fuel pump for a few seconds turn the key back of for about a half minute or so and turn key back on and repeat one more time and then start it did start like normal? Let me know what you find and will go from there.
