I've been fighting same general issue with starting. Try "Fuel Pump Relay" search with Jeep thrown in there. Several symptoms of rlay problems, you have most of them, I only had one (trying to start it) I'm thinking mine's OK, need a fuel pump and check valve. YOURS OTOH is sure sounding like it could be the relay.
