Make sure it's getting spark. If the spark is there, then go to the carb and make sure it's getting fuel. Those are the two things needed for combustion along with air. Sometimes new parts can be bad too.

How long since it last ran?
Confirm fuel flow to carb when cranking.
Confirm spark to plugs.
What were you doing to the Jeep last?
