With the older Jeeps and vehicles it was easy to check for spark and fuel, but the new EFI and coil on plugs have this old man at a loss. Just how do test for spark with a coil on plug as in a 2000 4.0L engine? How about testing for fuel on this same engine. On the older Jeeps you could pull a plug to check for spark and look into the carburetor or throttle body injection system and see the press of fuel being delivered.
