Hey guys. I have a 2003 Rubicon with a fuel system issue. A couple days ago I was on the road, bought gas on the way home, then parked overnight. Yesterday I got in it to go to work and it would crank, but not start. My fuel needle was at zero, but I know there is gas! At first I suspected fuel theft, but I ruled that out (I shook the jeep and can hear the gas sloshing around). I tried replacing the relay with no luck. Is there anything else I can try before spending hundreds of dollars and an afternoon dropping my fuel tank? I'd appriciate any help! Thanks!
